APOS Release Note Voice over IP
Added Features 1. STUN
STUN (Simple Traversal of User Datagram Protocol (UDP) Through Network Address Translators (NATs)) supported by APOS™ is designed based on the features of RFC3489. STUN is a standard protocol based on UDP, and allows AddPac Gateway to connect to another gateway that has a public IP in an NAT/firewall environment. The “public-ip” command enables a connection to a public IP in a private environment. If the public IP mapped with a private IP is changed frequently, the manager should set the “public-ip” command again. The STUN feature of APOS can resolve this issue. If the interface IP of a device is changed, this feature allows you to send an STUN message to the STUN server and receive the changed public IP to update the public IP. If a public IP is changed from the NAT server, you can check the changed public IP by checking periodical STUN messages. The STUN server operates just like other servers. The STUN server has a simple request and response architecture. The server, which is located at a public IP bandwidth, processes the data received from STN Client and sends the result to STUN Client. Number of the standard UDP port used by STUN is 3478.
Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

3. qos-threshold
The APOS VoIP product family allows you to check data on delay, jitter, and packet loss of the recent calls. If you set the threshold value of delay, jitter, and packet loss that may affect calling quality, the data on a call that exceeds the threshold value will be transferred to the SNMP trap. Also, the APOS VoIP product family provides the data on quality of recent calls when a request for SNMP Get is made. You can check the data from SNMP MIB. Currently, SIP supports the feature.

4. PPTP Route Data
Point-to-Point Tunneling Protocol (PPTP) supported by APOS™ conforms to RFC2637. If you can access the PPTP server through the LAN interface, you could use the PPTP feature to configure Virtual Private Network (VPN). PPTP supported by AddPac Gateway is a client feature that allows you to access the PPTP server; thus, a PPTP server must exist on the Internet. In the past, VoIP and data have been transferred through a tunnel by using the traditional PPTP route tunnel; however, you can execute the newly added “PPTP route data” command to enable only VoIP to be transmitted through a tunnel. Perform the setting below to configure a tunnel through which VoIP packets will be forwarded and to forward data packets to WAN: (config-ether0.0)# encapsulation ppp-pptp For information on the detailed configuration procedure, refer to ‘Related Commands’. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

5. Connection Delay
Typically, PBX does not deliver a message related to connections; thus, call duration of the actual users may be different from the amount of time it will take to perform billing by using a CONNECT message if a network where PBX is used is configured. In such a case, you can enable a CONNECT message to be forwarded in a specific amount of time by executing the relevant commands. Note that an outgoing call should be connected by one stage dialing. The example below shows that “prefix” configuration is performed on the VoIP gateway for “one stage dialing”.
Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

6. caller-id gain
AddPac Gateway receives the CID information as well when receiving a VoIP call, and displays the information on the phone. Typically, frequency modulation is performed on a network, while frequency demodulation is performed at the CID terminal. Frequency modulation should meet the standard characteristics of 1,200 Baud defined under the Bellcore recommendations for a channel for omni-directional data transfer. If AddPac Gateway delivers CID properly but the other party cannot recognize the CID, you can change the signal level required for modulation by using the relevant commands. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

7. Timeout tvcc
If voice is transmitted and a connection cannot be made in a configuration where a VoIP call is made through PBX even if the recipient hangs up the phone, you can enable a Disconnect message to be sent to the caller in a specific amount of time by executing the related commands. If a Connect message is not sent from PBX (For instance, an internal user does not answer a call), you can enable a Disconnect message to be sent to the caller in a specific amount of time set in the timer by executing the relevant commands. Note that an outgoing call should be connected by one stage dialing just like in Connection Delay. Also, the command below must be set to enable voice-confirmed-connect timeout: (config-vservice-voip)# voice-confirmed-connect

9. FXS Port PSTN-Backup-Port
If the gateway is in busyout mode, the cause would be one of the following: First, the power supply is blocked. Second, the LAN interface of the VoIP gateway is down. Third, the VoIP gateway cannot be connected to the other VoIP gateway because the gatekeeper, MGC, and proxy server are down. The SIP proxy server does not control the busyout mode. If a VoIP-peer connection fails, enable the hunt feature to perform hunting for the POTS-peer setup at the PSTN backup port. If the gateway is in busyout mode, it will be difficult to make a call over VoIP. In such a case, you can continue to open a network over PSTN. If PSTN backup is enabled, enable the busyout feature in the following method: Gateway(config-vservice-voip)# busyout monitor gatekeeper Gateway(config-vservice-voip)# busyout monitor callagent Gateway(config-vservice-voip)# busyout monitor voip-interface If the PSTN port exists at the VoIP gateway, the feature will not need to be enabled. If the gateway has only the FXS and FXO ports and you want to enable PSTN backup, execute the “PSTN-Backup-port” command at the FXS port. This feature enables the FXO port to operate just like the PSTN port. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

10. Restricting Call Duration
The “timeout tterm” command that restricts call duration has been executed for origination and reception as well as all ports of the VoIP gateway once the command is set. The “timeout tterm” command had been set as follows: (config)# voice service voip (config-vservice-voip)# timeout tterm <10 - 86400> The command has become to be executed in order to restrict only call duration at the target port. Since this command can be executed for any incoming and outgoing calls as well as any ports for VoIP services, you can use this command within the range you want. Note that the command is not executed and the timer does not operate until the caller lifts the handset. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

11. Changing FAX Scenario In the past, a call has been disconnected automatically once a facsimile was sent; however, in v8.21 or later, a call is not disconnected and RTP continues to be used even after a facsimile is sent. You can have a conversation with the other party after a facsimile is sent. If necessary, the facsimile can be retransmitted. Any and all VoIP products of AddPac Technology support this feature. This feature is supported by the g711a/ulaw, g7231r63/53, and g729 codecs of the H323 protocol; however, is not supported by the g726r32/16 codecs and SIP.

12. busyout monitor callagent
If communications are not properly made with the gatekeeper due to a network failure or another error or a call cannot be delivered properly via the VoIP network, the gateway will provide the busyout monitoring service in a configuration that enables automatic transfer to PSTN. This command has been added to monitor binding with CallAgent. If binding with CallAgent is disconnected, execute the “busyout monitor callagent” command to enter busyout mode. The command inter-works with the “busyout-timer” command in mgcp setting mode. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

13. rtp-nat-pat
If a gateway that has a private IP in the NAT/PAT environment attempts a call by using SIP, the call attempted from outside to the private gateway could not be made properly since the NAT/PAT server will not be able to know the RTP port used for the private gateway. In such a case, you can use the relevant commands to enable the NAT/PAT server to make a call properly by using the mapping table as follows: 1. The private gateway receives an INVITE message from outside. 2. The private gateway transfers the information on its RTP port to outside through the “rtp dummy packet” by using the INVITE message. 3. The NAT/PAT server reads the “rtp dummy packet” so that the mapping table can have the data on the RTP port used for the internal gateway. 4. If RTP is actually delivered from outside, the NAT/PAT server will use its mapping table to make a call properly. This feature has been implemented under SIP. The H323 protocol will support the feature. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

[Figure 15] SIP Attended Call Transfer Mode
If you want to transfer a VoIP call while you are on the phone as shown in Figure 11, press the hook flash button on the phone. In such a case, the GW2 (Transferee) user will be on hold and hear a dial tone. The user presses the phone number of GW3 (Target) to be transferred. Then, the user will hear a tone, and operation methods are different in each call transfer mode. In Basic (Blind) Transfer mode, GW1 (Transferor) transfers a call to the GW3 user, and the GW1 user hangs up the phone. In Attended Transfer mode, the GW1 (Transferor) user transfers a call to GW3 (Target). Then, the GW3 user could make a call to the GW1 user if the GW3 user lifts the handset. This is a big difference between the two modes. The GW3 user may hang up the phone after the GW1 user transfers a call to the GW3 user.

15. SIP Conference-server
A conference call allows more than two users to make a call. AddPac Gateway uses SIP to support 3-party conference calls. A separate conference server is required to enable this feature since AddPac Gateway itself does not support a conference call. It has been verified that a conference call is properly made by using Nortel Multimedia Communication Server (MCS) and Nortel Conference Server. The settings below are required to enable the conference call feature: (config)# dial-peer call-transfer h
(config)# dial-peer call-hold h The hook flash button on the phone is used to enable this feature. Press the hook flash button twice. This is the difference between call transfer. By default, the duration that AddPac Gateway recognizes the hook flash button is 500 ms. You should press the button for 500 ms (0.5 second) or less. If you think that 500 ms (0.5 second) is too short or the duration that PBX recognizes the hook flash button is 500 ms or more, you should change the hook flash detect timeout value. Refer to Step 4 of Related Commands. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

16. SIP enable-ping
This feature is specific to Nortel. If AddPac Gateway operates in the PAT/NAT or firewall environment, a VoIP call will fail to be connected. A gateway in a private environment can exchange packets from an external public network through the PAT/NAT server; however, since a network device on an external public network cannot be aware of the IP and port No. of a gateway in a private environment, an incoming VoIP call cannot be made. To make incoming and outgoing VoIP calls in a private environment, you should set the public IP address of the PAT/NAT server at the gateway and enable the information on the VoIP port used for the gateway to be mapped with the PAT/NAT server statically. If you use Enable-Ping of Nortel to address this problem, you could make communications with SIP Proxy of Nortel and make an incoming/outgoing call to SIP Proxy properly. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

17. SIP Media-channel [early|late]
The media channel refers to the RTP/RTPC route for making a VoIP communication. The media channel is categorized into the Tx channel and Rx channel for VoIP communications. This feature allows you to set a time when the Tx channel is enabled. If the gateway operates in the PAT/NAT environment and an inband (RTP) ringback tone (as well as color ring) is sent from the VoIP device of the other party, the inband ringback tone could not be delivered to the gateway in a private environment. The cause is the same as the one described in 12. SIP Enable-ping. To address this problem, open the Tx channel upon receiving 18X SDP after the gateway sends an INVITE message to the channel in a private environment. Then, a port table will be created at the PAT/NAT server so that you can hear an inband ringback tone. The media channel is categorized as follows: First, the default mode allows you to open the Tx channel only when receiving 183 Progress SDP after an INVITE message is sent. Even if 180 SDP is received, the Tx channel will not be open. Second, the early mode allows you to open the Tx channel when receiving 18X SDP after an INVITE message is sent. 18X SDP means that a 180 ring message includes SDP or a 183 progress message includes SDP. Third, the late mode allows you to open the Tx channel only when 200 OK is received after an INVITE message is sent. The Tx channel is not open when 18X SDP is received. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

18. SIP Remote-party-id
If you want to apply the user name not E.164 defined in the destination pattern to the From field when an INVITE message is sent, enable this feature. AddPac Gateway supports a feature specific to Nortel. Typically, a caller ID refers to the user ID from the From field. If an IP phone inter-works with the trunk gateway at Nortel, a string will be used as the user ID and the caller ID will be converted to digits at SIP Proxy Server. In such a case, since SIP Proxy cannot convert the From field, it uses an option field, remote-party-id, to create, detect, or display the caller ID. This feature enables AddPac Gateway to inter-work with the VoIP device provided by Nortel. The Remote Party ID field is created in FXO, E&M, and E1/T1-type modules of AddPac Gateway not in the FXS-type module. Note that a remote party ID is not created in the FXS-type module even if this feature is enabled. All modules of AddPac Gateway recognize a caller ID by referring to the Remote Party ID optional field, if any, when receiving an INVITE message. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

SIP can enable the call diversion feature, which has been supported only by H.323. The SIP call diversion feature supported by AddPac Gateway enables a call to be transferred to another gateway when the recipient is on the phone, does not answer the call, or is in unconditional mode. If the recipient does not answer a call, a sound will ring for 15 seconds from the phone of the recipient and then call diversion will be performed. The unconditional mode enables any calls to be transferred to another gateway if the original gateway has a failure. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

31. MGCP dtmf-relay dual-mode
There are two digit delivery methods of dtmf-relay rtp-2833 and out-of-band to make a VoIP call using MGC. rtp-2833 enables a digit to play as long as the digit is pressed when the digit is entered after a call is made. Out-of-band transmits event logs on which digits have been pressed not how long a digit is pressed. An NTFY message including the relevant event log is forwarded to MGC. If you want to forward an NTFY message by playing a digit as long as the digit is pressed, enable dtmf-relay dual-mode. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

32. MGCP epid-type
Epid-type allows you to name an endpoint-id type. An epid-type should match the epid type required for authentication in MGC. Epid-type is categorized into two types as follows: First, the default type of an endpoint name is specified by using the information on slots/ports, and is displayed in the form of “aaln/slot/port@hostname”. Second, the specific type of an endpoint name is specified by using the counter information not slots/ports, and is displayed in the form of “aaln/counter@hostname”. Note that the counter starts from 1 not 0. A character specified such as “epid-type s# p#” can be added to the left of #. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

33. FAX protocol ‘multi-session-t38’
A facsimile session opens after the re-invite message containing the information on “T38 CED Tone” is forwarded once “T38 CED Tone” arrives after the audio session opens. If you want to close the audio session and to maintain only the facsimile session when the audio session and facsimile session open simultaneously, you can enable the feature. If the audio and facsimile sessions are open simultaneously before ‘CED Tone’ is detected, it means that the audio session is activated and the facsimile session is on hold. In Version 8.23, this feature can be enabled only under MGCP. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

34. MGCP force-local-rt
If an outgoing call is made via the VoIP gateway and the ‘rt’ data of the mdcx message received from MGC is received, a local ringback tone will be played. If the other party receives an inband ringback tone, the tone will be played. An inback ringback tone from the other party is mute, and a ringback tone plays back. Sometimes, a mute ringback tone plays back. In such a case, you can use the “force-local-rt” command. If an inband ringback tone is heard while a local ringback tone is playing back, ignore the inband ringback tone and continue to play back the local ringback tone before a call is connected. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

35. E1/T1 compand-type [au-law|ua-law]
PBX has two types: a-law (Europe), which is the traditional PBX, and u-law (North America), which is a new PBX. When you use only a-law (Europe), a problem had not occurred while PBX is being used. As u-law (North America) was developed, PBX has conformed to u-law, and the E1 card contained in PBX has conformed to a-law. You can maintain the proper operation of PBX by adjusting the compand-type in the PCM mode/signal mode. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

36. E1/T1 isdn overlap-sending
Once the recipient sends setup ACK to the setup message received over VoIP, AddPac Gateway sends the setup ACK indicate data to the caller. In such a case, each character of a digit pressed by the caller is delivered to PBX in the form of information, and the PBX sends alert. An RTP communication path is established between the caller and recipient under H245. If a called number does not exist in the setup message sent from outside over VoIP, PBX itself will not be able to recognize DTMF and only the current flows while a call is connected. In such a case, execute the relevant commands to make a call properly. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

37. E1/T1 clock slave-main
This feature is used for a gateway model where 4E1 is installed. If the gateway enters in clock slave mode, a failure in facsimile reception may occur; thus, the slave-main setting is required for one controller port of 4E1. The slave-main setting can be performed only in one of four ports. Note that the slave setting is automatically performed in the other three ports when the slave-main setting is performed in one port. Any and all VoIP products of AddPac Technology support this feature. You can enable or disable the feature.

38. ISDN PRI numbering-type
If the numbering type of the called/calling number among the setup messages received from the external (originating) gateway is PRI, it always will be a unknown type. To resolve this issue, the three types of commands below have been added. 1. isdn called(calling)-party-numbering-type { abbreviated | international | national | network | subscriber | unknown } 2. isdn called(calling)-party-numbering-type by-peer 3. isdn called(calling)-party-numbering-type from-network In No. 1, the numbering type defined in MG3000N PRI is applied to the setup message forwarded from MG3000N to PBX. In No. 2, the numbering type setting in POTS-peer/VoIP-peer is delivered to PBX as is. In No. 3, the numbering type is delivered to PBX by referring to the numbering type field of the setup message forwarded from the external (originating) gateway. Any and all VoIP products of AddPac Technology where the E1/T1 module can be installed support this feature. You can enable or disable the feature.
