Restrictions for Video Conferences and Video Transcoding

Restrictions for Video Conferences and Video TranscodingThe following section describes some restrictions about the video conferencing and transcoding feature.

• For a Cisco Unified IP phone 7985 that is registered with Cisco Unified CME to participate in a video conference, the phone requires a DSP farm profile that is configured with the H.263 codec. Cisco Unified IP Phones 7985 connected to Cisco Unified Communications Manager can support both H.263 and H.264.

• Cisco Unified IP Phones 9951 and 9971 has the following interoperability issues:

– Cisco Unified IP Phones 9951 and 9971 require a DSP farm profile that is configured with the H.264 codec.

– When you enable the lecture mode option on Cisco Unified CME, a conferee on Cisco Unified IP Phones 9951 and 9971 cannot become a lecturer. Users on the phone can only participate in the video conference as conferees.

– Cisco Unified IP Phones 9951 and 9971 use the Real-Time Transport Protocol (RTP) payload value of 97. This value is often reserved for cisco-codec-fax-ack. You must reconfigure your RTP payload for cisco-codec-fax-ack and for cisco-codec-video-h264 by adding the following commands to the appropriate dial-peer profile

rtp payload-type cisco-codec-fax-ack 111

rtp payload-type cisco-codec-video-h264 97

• Lifesize endpoints using 4cif resolution display a blank screen when a conferee on a Cisco Unified IP Phone 9951 or 9971 with qcif resolution becomes the active speaker. The display correctly displays all other conferees.

Adhoc conferences on endpoints that are connected through a SIP trunk are currently not supported. However, endpoints that are connected through a SIP trunk can connect to meetme video conferences.

Video TerminologyYou should be familiar with the terminology in Table 3 before you configure video conferences and video transcoding.

Table 3 Video Conference Terminology

Terminology Description

Homogeneous Conference

(Switching)

A conference in which conferees connect to a video conference bridge with phones that support the same video format attributes (same codec, resolution, frame rate, bit rate, RTP payload protocol and annex).

For more information, see the “Homogeneous Video Conferences” section on page 7.

Heterogeneous Conferences

(Switching and Transcoding)

A conference in which conferees connect to a conference bridge with phones that support different video format attributes.

For more information, see the “Heterogeneous Video Conferences” section on page 8.

Transcode The process of converting one data stream using one codec format to another data stream with a different codec format, for example, coverting H.263 to H.264.

Transrate The process of converting one data stream using one bit rate to another data stream with a different bit rate, for example, converting from a high-speed data rate of 2 Mbps to a lower-speed data rate of 1 Mbps.

Transsize The process of converting the resolution of a video transmission to another resolution, for example converting 4CIF to CIF.

Video Conference Bridge A video conference bridge enables conferees to connect to a video conference.

For more information, see the “Overview on Video Conferences” section on page 7.

Video Conversion The process of transcoding, transrating, or transsizing a video stream.

Video Format The attributes of the video stream (video codec, resolution, frame rate, bitrate, RTP payload protocol, and annex).

Video Capability Class Video Capability Class defines a set of attributes (codec, frame rate, bit rate, resolution, RTP payload protocol, and annex) that comprise the video format of a data stream for a group of endpoints. A video capability class comprises an encoder and decoder pair.

For more information, see the “Video Capability Class” section on page 8.


OL-25133-01


Overview on Video ConferencesA video conference bridge brings together three or more callers on a variety of video phones in ad hoc or meetme conferences.

In ad hoc conferences, a participant on a phone call initiates a video conference by adding another participant. In an ad hoc conference, you can configure the conference bridge to support up to a maximum of eight conferees.

In meetme conferences, callers dial a designated number that has been designated as a video conference bridge. Callers on supported video phones are connected to the conference bridge as video conferees. In a meetme conference, you can configure the conference bridge to support up to 16 conferees.

Note Meetme conferences on Cisco Unified Communications Manger systems can only be initiated on phones with a meetme button.

On a Cisco Unified Communications Manager Express, you can configure an unlocked meetme conference to allow any phone to dial the configured meetme number to start a new conference or join an active conference.

Note Callers on unsupported phones are connected to the conference bridge as audio conferees.

Display View

Conferees in a video conference may have different display views.

• Voice Activated Switching—(Default Display View) The Display screen switches to the loudest speaker, typically the current active speaker. The screen for the current active speaker displays the previous active speaker.

• Lecture Mode—The display screen focuses on a single participant. You can configure a DTMF sequence in Cisco Unified Communications Manager Express to allow a conferee to become the lecturer. When the caller enters the DTMF sequence, the caller becomes the lecturer and all other conferees see the lecturer. The lecturer sees a round-robin display of all other conferees.

Homogeneous Video Conferences

A homogeneous video conference is a conference in which participants connect to a conference bridge on video phones that support the same video format. Figure 1 illustrates a homogeneous video conference. All the video phones support the same video format and the conference bridge sends the same data stream format to all the video conferees in the conference. If the conference bridge is not configured to support a phone’s video format, the caller on the phone connects to the conference as an audio only conferee.

Note In a homogeneous conference, the DSP resource for the video bridge is reserved and homogeneous video service is guaranteed. Conferees use the same video stream that is configured in the video profile.


OL-25133-01


Figure 1 Homogeneous Video Conference

Heterogeneous Video Conferences

A heterogeneous video conference is a conference in which conferees can connect to a conference bridge on video phones that support different video formats. In a heterogeneous conference, you can reserve DSP resources to ensure all phones with different capabilities have video service.

For heterogeneous conferences, callers are connected to the conference as audio conferees under the following condition:

• Insufficient DSP resources.

• The video conference bridge is not configured to support the phone’s video capabilities.

Video Capability Class

A video capability class defines the set of attributes (codec, frame rate, bit rate, resolution, RTP payload protocol, and annex) that comprise the video format of a data stream and a video capability class comprises an encoder and decoder pair.

At the start of the conference, the phones negotiate the video format, and phones with the same video format are grouped into the same video capability class. Phones supporting a different video format are grouped into a different video capability class. The router dynamically converts multiple data stream as needed for the different video capability class.

Figure 2 illustrates a heterogeneous video conference with three different video capability class and a phone that is connected by an audio connection.

Guaranteed Audio

If you have limited DSP resources, you can reserve DSP resources for just the audio conference bridge. The DSP resources for the audio conference bridge are reserved, but video service is not guaranteed. Callers on video phones may have video service if DSP resources are available at the start of the conference. Otherwise, the callers are connected to the conference as audio conferees.

Overview of Point-to-Point Video TranscodingIf the video phones on a call support the same video format attributes, the router can pass the video data stream from one phone to another phone without altering the data stream. Video phones have many different video formats and phones that support different video formats cannot communicate directly with one another.

To enable the two phones that are using different video formats to communicate with one another, you can configure the router to dynamically convert (encode and decode) the video data stream between the two phones.

DSP Farm Profiles To allocate DSP resources to support video transcoding, transrating, and transsizing on a video call, you must create DSP farm profiles and specify the video format that is supported. This ensures that the system has sufficient resources available for video stream conversion.

Table 5 and Table 6 list the supported video resolution, frame rate, and bit rate support for H.263 and H.264, respectively, for both video conferences and video transcoding on a video call.

Important Considerations

To support a video conference in which all phones support the same video format, you can configure a homogenous DSP farm profile. The homogenous DSP farm profile has one video format.

To support a video conference in which phones may have different capabilities, you can configure a heterogeneous DSP farm profile. A heterogeneous conference profile reserves the DSP resources for converting the video data stream based on the configured maximum number of conferees, maximum number of conference sessions, and the number of video capability class.

You can also configure the system to support phones with different capabilities without reserving the DSP resources for converting the video data streams. The system supports a conference bridge as long as resources are available at the start of the conference. When there are insufficient resources, conferees have an audio-only connection.

Calculating DSP RequirementsTo determine whether you have sufficient PVDM modules, you can use the DSP Calculator at

http://www.cisco.com/web/applicat/dsprecal/dsp_calc.html.

Important ConsiderationsBefore you proceed with configuring video conferences, consider the following requirements and recommendations:

• It is essential that you are familiar with the video capabilities of the phones in your network. Be aware that heterogeneous conference profiles use significantly more DSP resources than either homogeneous conferences or guaranteed audio profiles. If all the phones support the same video format, you should configure a DSP farm profile for a homogeneous conference.

• When provisioning phones in the network, configure the phones to support a wide number of video capabilities.

4CIF (4SIF) 30 f/s 1 Mb/s to 2 Mb/s

Note Conference supports 1 Mb/s only.

VGA 30 f/s 1 Mb/s to 2 Mb/s

w448P 30 f/s 1 Mb/s to 2 Mb/s

How to Configure Video Conferences and Video Transcoding

• You can reduce your DSP resource usage by limiting the video capability class for a heterogeneous video conference. Many endpoints with higher capability can support lower video formats. For example, H.264 4CIF endpoint can support H.264 CIF video. Consider configuring your DSP profile to support lower encoder capabilities to optimize your DSP usage.

• When you configure a codec resolution in your heterogeneous DSP farm profile, you may need to explicitly configure all resolutions for the same codec. For example, if you have phones that support CIF and other phones that support only VGA and you want to ensure that phones with either resolution can join the conference, you must explicitly configure both CIF and VGA in the DSP farm profile. This also applies to point-to-point video transcoding DSP farm profiles.

How to Configure Video Conferences and Video TranscodingThis section contains the following task:

• Configuring DSP Farm Resources for Video Conferences

Problems with the Video Conference not Displaying

Symptom Phone connects to the conference, but the phone does not display any video.

Possible Cause 1: There may be insufficient DSP resources or negotiation failed.

Recommended Action If all DSP resources for video are in use, you can increase the DSP resources available for video conferencing and transcoding by decreasing the percentage of DSP resources that is reserved for voice services with the voice-service dsp-reservation command.

Possible Cause 2: Limit for video cap-class has been reached.

Recommended Action When the maximum number of video-cap-class is reached, the participant who is using a phone that requires a different video format will connect as an audio participant only. Participants who are using a phone with video format that is supported by a video-cap-class will be connected as video participants.

Possible Cause 3: The endpoint device does not support the configured codec.

Recommended Action Verify that the devices support the configured codec and that the dspfarm profile supports that codec.

Possible Cause 4: Incorrect media payload type.

Recommended Action Verify that you have the correct media payload by checking the media payload on the sniffer trace or by viewing the output from show dspfarm video conference.

Phone cannot Join the Conference

Symptom Phone cannot join the conference even though the number of conferees is less than the number of maximum conference participant configured in the DSP farm profile. .

Possible Cause : The maximum number of participants that is configured in Cisco Unified Communications Manager is smaller than the maximum number of participants that is configured in the DSP farm profile.

Recommended Action Confirm that the Maximum Ad Hoc Conference and Maximum Meetme Conference Unicast parameters in Cisco Unified Communications Manager Administration (System > Service Parameters) is less than or equal to the maximum conference participant value specified in the DSP farm profile and modiffy the parameters on the Cisco Unified Communications Manager.

Unable to Register a Profile

Symptom Video profile cannot register with a Cisco Unified Communications Manager.

Possible Cause Video Conferencing is not supported on this version of Cisco Unified Communications Manager.

Recommended Action Upgrade to Cisco Unified Communications Manager, version 8.6 or later.

No Line Available

Symptom Phone displays “No Line Available” message.

Possible Cause 1: There are no conference profiles.

Recommended Action Configure a conference profile.

Possible Cause 2: DSP farm has not been registered or configured properly.

Recommended Action Configure and register the DSPfarm.

For homogeneous video profiles, only one video format is supported

Release Modification

12.3(8)T This command was introduced.

12.4(4)T The pass-through keyword was added.

12.4(11)XJ2 The gsmefr and gsmfr keywords were removed as configurable codec options for all platforms.

12.4(15)T This command was integrated into Cisco IOS Release 12.4(15)T.

12.4(15)XY The g722r-64 keyword was added.


12.4(22)T Support for IPv6 was added.

15.1(1))T This command was modified. The isac keyword was added.

15.1(4)M This command was modified to add codec support for ilbc, h.263 and h.264. The frame-rate, bitrate, rfc-2190, and pass-through keywords were added


OL-25133-01


For heterogeneous and heterogeneous guaranteed-audio video profiles, multiple video formats and audio codecs are supported.

To change the configured codec in the profile, you must first enter a no maximum session command.

Table 9 shows the relationship between DSP farm functions and codecs.

Hardware MTPs support only G.711 a-law and G.711 mu-law. If you configure a profile as a hardware MTP and you want to change the codec to other than G.711, you must first remove the hardware MTP by using the no maximum sessions hardware command.

The pass-through keyword is supported for transcoding and MTP profiles only; the keyword is not supported for conferencing profiles. To support the Resource Reservation Protocol (RSVP) agent on a Skinny Client Control Protocol (SCCP) device, you must use the codec pass-through command. In the pass-through mode, the SCCP device processes the media stream by using a pure software MTP, regardless of the nature of the stream, which enables video and data streams to be processed in addition to audio streams. When the pass-through mode is set in a transcoding profile, no transcoding is done for the session; the transcoding device performs a pure software MTP function. The pass-through mode can be used for secure Real-Time Transport Protocol (RTP) sessions.

Examples The following example shows how to set the call density and codec complexity to g729abr8:

conference (ephone-dn)

An unlocked meet-me conference allows the user to unlock the meet-me conference bridge. All DN tags with the same number should be configured with the unlocked option. Unlocking the meet-me conference bridge can allow unrestricted and uncontrolled access for the external callers. This feature is support only for meet-me conferences.

When you unlock meet-me conference bridge in Cisco Unified CME, the user can initiate a meet-me conference without pressing the MeetMe softkey, which would allow the external callers to initiate a meet-me conference.

Note To configure an unlocked meet-me conference, all ephone-dn tags associated with the same number should have the unlocked option configured. If some of the ephone-dn tags do not have the unlocked option configured, the unlocked meet-me conference may not work properly.

Use the ephone-dn command to configure enough extensions for your conference needs. Each extension can handle two conference parties if the dual-line keyword is used with the ephone-dn command, as shown in the following example. Use the show ephone-dn command to display phone information for the extension.

Examples The following example configures extension 9001 as a four-party meet-me conference number.

OL-25133-01

dspfarm profile

Command Default If this command is not entered, no profiles are defined for the DSP farm services.

Command Modes Global configuration (config)

Command History

Usage Guidelines Use this command to create a new profile or delete a disabled profile. After you create a new profile in dspfarm profile configuration mode, use the no shutdown command to enable the profile configuration, allocate resources and associate the profile with the application(s). If the profile cannot be enabled due to lack of resources, the system prompts you with a message “Can not enable the profile due to insufficient resources, resources available to support X sessions; please modify the configuration and retry.”

If the DSP farm profile is successfully created, you enter the DSP farm profile configuration mode. You can configure multiple profiles for the same service.

Use the no dspfarm profile command to delete a profile from the system. If the profile is active, you cannot delete it; you must first disable it using the shutdown command. To modify a DSP farm profile, use the shutdown command in dspfarm profile configuration mode before you begin configuration.

The profile identifier uniquely identifies a profile. If the service type and profile identifier are not unique, the user is prompted with a message to choose a different profile identifier.

heterogeneous (Optional) Specifies that video participants can use the different video formats that are configured in the profile. You can configure up to 10 video codecs in the heterogeneous profile. DSP resources are reserved to support the different configurations at configuration time.

guaranteed-audio (Optional) Specifies that video participants in a heterogeneous conference will at least have an audio connection. You can configure up to 10 video codecs in the guaranteed-audio profile. The DSP resources for audio streams are reserved at configuration time, but DSP resources to support video conferences are not reserved. If the video endpoint supports the video format specified in the profile and DSP resources are available when the participant joins the conference, the participant joins as a video conferee in the video conference.

dspfarm profile

You must use the security keyword in order to enable secure DSP farm services such as secure transcoding.

Effective with Cisco IOS Releases 15.0(1)M2 and 15.1(1)T, platform support for the Cisco IAD 2430, IAD 2431, IAD 2432, and IAD 2435, and the Cisco VG 202, VG 204, and VG 225 is modified. These platforms are designed as TDM-IP devices and are not expandable to install extra DSP resources. So even though the conference keyword appears in the command syntax, this DSP service is not configurable on these platforms. If you try to configure conferencing on these platforms, the command-line interface displays the following message: “%This platform does not support Conferencing feature.”

The transcode keyword also appears in the command syntax, but this DSP service is not available on the Cisco VG 202, VG 204, and VG 224 platforms. If you try to configure transcoding on these platforms, the CLI displays the following message: “%This platform does not support Transcoding feature.”

Cisco ASR 1000 Series Router

The support for dspfarm profile command was added on Cisco ASR 1000 Series Router from Cisco IOS XE Release 3.2 and later releases. The command is used to create a dspfarm profile for different services.

Note The secure DSP farm services is always enabled for SPA-DSP on Cisco ASR 1000 Series Router. Only transcode keyword is supported on Cisco ASR 1000 Series Router for Cisco IOS XE Release 3.2s. The conference, media, and security keywords are not supported on Cisco ASR 1000 Series Router for Cisco IOS XE Release 3.2s.

In order to configure a video dspfarm profile, you must set voice-service dsp-reservation to be less than 100 percent.

To enable dspfarm profiles for voice services, you must use the dsp services dspfarm command under the voice-card submode.

Examples The following example enables DSP farm services profile 20 for conferencing:

Router(config)# dspfarm profile 20 conference

Note the response if the profile is already being used:

Router(config)# dspfarm profile 6 conference

Profile id 6 is being used for service TRANSCODING please select a different profile id

The following example enables DSP farm services profile 1 for transcoding:

Router(config)# dspfarm profile 1 transcode

Video Conferences

The following example enables DSP farm services profile 99 for homogeneous video. The conference supports four participants under one format (Video codec H.263, qcif resolution, and a frame-rate of 15 f/s).

Router(config)# dspfarm profile 99 conference video homogeneousRouter(config-dspfarm-profile)# codec h263 qcif frame-rate 15 Router(config-dspfarm-profile)# maximum conference-participant 4

maximum conference-participants

maximum conference-participantsTo configure the maximum number of conference participants allowed in each meet-me conference, use the maximum conference-participants command in DSP farm profile configuration mode. To reset the maximum to the default number, use the no form of this command.

maximum conference-participants max-participants [video-cap-class number]

no maximum conference-participants max-participants [video-cap-class number]

Syntax Description

Command Default The default maximum number of participants for a video conference is 4. The default maximum number of participants for an audio conference is 8.

Command Modes DSP farm profile configuration (config-dspfarm-profile)

Command History

Usage Guidelines The maximum number of participants allowed for hardware conferencing is dependent on the codec used in the DSP farm profile. Use the codec command in DSP farm profile configuration mode to specify the codecs supported by the DSP farm profile. Use the show dspfarm profile command to display the DSP farm profile.

Examples The following example configures a DSP farm profile that has a maximum of 16 participants for hardware conferences using the G.711 codec:

Router(config)# dspfarm profile conference 1Router(config-dspfarm-profile)# maximum conference-participants 16Router(config-dspfarm-profile)# codec g711alaw

max-participants Maximum number of participants allowed in each meet-me conference session. One DSP can support the following maximums:

• G.711—32 participants

• G.729—16 participants

• Video (H.263 or H.264)—4, 8, or 16 participants

video-cap-class number

(Optional) Reserves the DSP resources needed to support a video participant requiring video format conversion. The range for video port number is from 2 to 4. The default is 2.

media

mediaTo enable media packets to pass directly between the endpoints, without the intervention of the Cisco Unified Border Element (Cisco UBE) and to enable signaling services, enter the media command in dial peer voice, voice class, or voice service configuration mode. To return to the default behavior, use the no form of this command.

media [flow-around | flow-through | forking | monitoring [max-calls] | statistics | transcoder high-density | anti-trombone | sync-streams]

no media [flow-around | flow-through | forking | monitoring [max-calls] | statistics | transcoder high-density | anti-trombone | sync-streams]

Syntax Description

Command Default The default behavior of the Cisco UBE is to receive media packets from the inbound call leg, terminate them, and then reoriginate the media stream on an outbound call leg.

Command Modes Dial peer voice configuration (config-dial-peer)Voice class configuration (config-class) Voice service configuration (config-voi-serv)

Command History

flow-around (Optional) Enables media packets to pass directly between the endpoints, without the intervention of the Cisco UBE. The media packet is to flow around the gateway.

flow-through (Optional) Enables media packets to pass through the endpoints, without the intervention of the Cisco UBE.

forking (Optional) Enables the media forking feature for all calls.

monitoring (Optional) Enables the monitoring feature for all calls or a maximum number of calls.

max-calls (Optional) The maximum number of calls that are monitored.

statistics (Optional) Enables media monitoring.

transcoder high-density (Optional) Converts media codecs from one voice standard to another to facilitate the interoperability of devices using different media standards.

anti-trombone (Optional) Enables media anti-trombone for all calls. Media trombones are media loops in SIP entity due to call transfer or call forward.

12.4(20)T This command was modified. The transcoder and high-density keywords were introduced.


OL-25133-01

media

Usage Guidelines With the default configuration, the Cisco UBE receives media packets from the inbound call leg, terminates them, and then reoriginates the media stream on an outbound call leg. Media flow-around enables media packets to be passed directly between the endpoints, without the intervention of the Cisco UBE. The Cisco UBE continues to handle routing and billing functions. Media flow-around for SIP-to-SIP calls is not supported.

Note The Cisco UBE must be running Cisco IOS Release 12.3(1) or a later release to support media flow-around.

You can specify media flow-around for a voice class, all VoIP calls, or individual dial peers.

The transcoder high-density keyword can be enabled in any of the configuration modes with the same command format. If you are configuring the transcoder high-density keyword for dial peers, make sure that the media transcoder high-density command is configured on both the in and Out-Legs.

Note The software does not support configuring the transcoder high-density keyword on any dial peer that is to handle video calls. The following scenarios are not supported:

• Dial peers used for video at any time. Configuring the media transcoder high-density command directly under the dial-peer or a voice-class media configuration mode is not supported.

• Dial peers configured on a Cisco UBE used for video calls at any time. The global configuration of the media transcoder high-density command under voice service configuration mode is not supported.

To enable the media command on a Cisco 2900 or Cisco 3900 series Unified Border Element voice gateway, you must first enter the mode border-element command. This enables the media forking and media monitoring commands. Do not configure the mode border-element command on the Cisco 2800 or Cisco 3800 series platform.

You can specify media anti-trombone for a voice class, all VoIP calls, or individual dial peers.

The anti-trombone keyword can be enabled only when no media interworking is required in both the Out-Legs. Antitrombone will not work if call leg is flow-through and another call leg is flow-around.

Examples Media Flow-around Examples

The following example shows media flow-around configured on a dial peer:

Router(config)# dial-peer voice 2 voip Router(config-dial-peer)# media flow-around

The following example shows media flow-around configured for all VoIP calls:

mtp

mtpTo send voice packets from an IP phone to the Cisco Unified CME router, use the mtp command in ephone or ephone-template configuration mode. To return to the default, use the no form of this command.

mtp {video-only | both}

no mtp {video-only | both}

Syntax Description

Command Default If no arguments are given, only voice packets are sent to the router.

An IP phone in a call with another IP phone in the same Cisco Unified CME system sends voice and video packets directly to the other phone.

Command Modes Ephone configuration (config-ephone)Ephone-template configuration (config-ephone-template)

Command History

Usage Guidelines Normally, media packets (RTP packets) that are sent between IP phones in the same Cisco Unified CME system go directly to the other phone and do not travel through the Cisco Unified CME router. When these packets are sent from a remote IP phone to another IP phone in the same Cisco Unified CME system, they may be obstructed by a firewall. The mtp command instructs a phone to always send its media packets to the Cisco Unified CME router, which acts as a proxy and forwards the packets to the destination. Firewalls can then be easily configured to pass the RTP packets because the router uses a specified UDP port for media packets. In this way, RTP packets from remote IP phones can be delivered to IP phones on the same system. The default is that this function is off and that RTP packets that are sent from one IP phone to another IP phone in the same Cisco Unified CME system go directly to the other phone.

If you use an ephone template to apply a command to a phone and you also use the same command in ephone configuration mode for the same phone, the value that you set in ephone configuration mode has priority.

video-only Specifies that the video streams must be sent through the Cisco Unified CME route.

both Specifies that both voice and video streams must be sent through the Cisco Unified CME route.

show sccp

Usage Guidelines The router on which you use the show sccp command must be equipped with one or more digital T1/E1 packet voice trunk network modules (NM-HDVs) or high-density voice (HDV) transcoding/conferencing DSP farms (NM-HDV-FARMs) to provide digital signal processor (DSP) resources.

Use the show sccp ccm group command to show detailed information about all groups assigned to the Cisco Unified CallManager. The optional group-number argument can be added to select details about a specific group.

Configure the show sccp server statistics command on the Cisco Unified Border Element, IP-to-IP Gateway, or Session Border Controller where no SCCP phone is registered, to show the statistical counts on the SCCP server. The counts display queuing errors and message drops on the transcoder alone when it is on the Cisco Unified Border Element, IP-to-IP Gateway, or Session Border Controller.

When the show sccp server statistics command is used on the Cisco Unified Manager Express (CME), it is recommended for use together with the clear sccp server statistics command.

Examples In the following sample output, the gateway IP address can be an IPv4 or IPv6 address when it operates on an IPv4/IPv6 dual stack.
