2 SIP VoIP Settings applicationSIP VoIP Settings is a stand-alone application that enables voice over IP (VoIP) settings to be

configured on an S60 device. It can be used to create or modify VoIP profiles as well as to create

network address translation (NAT) firewall (FW) settings and modify the VoIP parameters, includingthe codec and NAT FW settings, which on S60 devices are typically invisible to users.

With the SIP VoIP Settings application, it is also possible to save all the VoIP profile settings to an Open

Mobile Alliance (OMA) Client Provisioning (CP) document and import OMA CP VoIP settings to an S60

device from an XML file.

Note: Editing is available for VoIP settings only in profiles created with the SIP VoIP Settings

application. The settings for a provisioned VoIP profile cannot be displayed or edited. Such a profile

can, however, be used as the basis of a new profile created using SIP VoIP Settings. The settings of

such a new profile can be displayed and edited.

The VoIP Settings application provides the following editing features: Create VoIP profile A VoIP profile can be created using a default or an existing VoIP profile or

using an imported XML-based CP document.

Delete VoIP profile VoIP profiles can be deleted. Save settings to file VoIP profile settings can be saved to an XML file. Edit VoIP profile settings Profile-specific VoIP settings can be viewed and modified. Select SIP profile The name of the Session Initiation Protocol (SIP) profile used in the VoIP

profile can be viewed and changed.

Create audio codec An audio codec can be created. Delete audio codec An audio codec can be deleted. Move audio codec The order (priority) of the codec can be updated. Edit audio-codec settings Audio-codec settings can be viewed and modified.The application provides the following features for editing NAT FW settings:

Create domain-specific settings Domain-specific settings can be created. Edit domain-specific settings Domain-specific settings can be viewed and modified. Delete domain-specific settings Domain-specific settings can be deleted. Create IAP-specific settings Internet Access Point (IAP) settings can be defined. Edit IAP-specific settings IAP-specific settings can be viewed and edited. Delete IAP-specific settings IAP-specific settings can be deleted.

3 VoIP servicesSIP VoIP Settings provides for the creation and maintenance of a VoIP profile, which includes VoIP-

service-specific settings, such as:

VoIP service name. VoIP service parameters. Speech-codec settings. SIP profiles used.In addition, features for importing and exporting VoIP profile settings are provided.

The VoIP profile name is the same as the VoIP service name that will be seen by a user of an S60

device when selecting a VoIP service. If a VoIP service provider also configures the access networks

used so that they have, for example, a different billing or connectivity mode, two or more VoIP profiles

are needed. If the service provider does not set up the access networks, only one VoIP and one SIPprofile are needed. The VoIP profile settings are then linked to the access point selected when the user

is successfully registered to the service.

To access the VoIP services, in the SIP VoIP Settings screen, select the VoIP services item, and then

choose Options > Open, as shown in Figure 1. Now a list of any available VoIP services is displayed,

though initially there may be none to display, as shown in Figure 2.

Figure 1: Select the VoIP services

item, and then choose Options >

Open.

Figure 2: Initially, no VoIP services

may be available.

The profile settings available are:

Provider Name:o Text, for which the maximum length is 32 characters.o

The provider of the VoIP profile settings as described in /R.1/ OMA-WAP-ProvCont-v1_1-20021112-C, which is displayed on the device UI as the sender of the settings and cannot

be edited.

Profile Name:o Text, for which the maximum length is 32 characters.o The profile name, based on the provisioning parameter NAME as described in /R.1/ OMA-WAP-

ProvCont-v1_1-20021112-C, which is displayed on the device UI as the service name.

Media QoS:o A number in the range of 063.o The Quality of Service (QoS) setting for VoIP media. The parameter value corresponds to the

DiffServ Code Point (DiffServ, DSCP bits) QoS values used in IP headers (Ipv4 TOS and Ipv6 TC)

or those defined by IETF Request for Comments (RFC) 2598, an Expedited Forwarding PHB [3].

The IETF and WMM [4] specifications conflict on the QoS values used for voice packets. From

S60 3rd Edition, Feature Pack 1 onward, the U-APSD power-save scheme of WMM is also

enabled with the IETF default value (46), if the feature is supported by the device and the

WLAN access point.

o Default value: 46. Start media port:

o An even number in the range of 102465534.o The lower limit of the real-time transport protocol (RTP) port range.o Default value: 49152.

End media port:o An even number in the range of 102465534.o The upper limit for the allocated RTP ports. The value must be at least 4 over the Start media

ports number to guarantee two simultaneous calls.

o Default value: 65534. DTMF inband:

o DTMF tones are sent as compressed audio; they are part of a VoIP calls audio stream. Notethat the DTMF tones may be degraded if a high-compression-rate codec (AMR-NB, G.729, oriLBC) is in use for a VoIP call.

o It is recommended that this value not be changed, because if enabled (see below) and ifsupported by the other peer in the VoIP call, the DTMF tones are sent as out-band.

o On: Enabled.o Off: Disabled.o Default value: On.


11/28

Forum.Nokia.com


DTMF outband:o DTMF tones are sent as RTP payload, as specified in IETF RFC 2833. If both in- and out-band

DTMF signaling methods are enabled (setting value 1), the DTMF out-band mode is used if the

peer supports it.

o Typically, both in- and out-band DTMF should be enabled; however, disabling the out-bandsignaling is required in some special cases.o On: DTMF digits out-band are generated, if requested by the remote side.o Off: DTMF digits out-band are not generated.o Default value: On.

Allow VoIP over WCDMA:o If this setting is enabled, the Internet telephone application shows the available WCDMA

access points.

o On: VoIP over WCDMA is allowed.o Off: VoIP over WCDMA is not allowed.o Default value: Off.

RTCP reporting:o This setting enables the RTCP reports defined in RFC 3550.o On: RTCP reporting is enabled.o Off: RTCP reporting is disabled.o Default value: Off.

UA Header: term. type:o On: The device type is appended to the UA header.o Off: The device type is not appended to the UA header.o Default value: On.

UA Header: MAC address:o Off: The MAC address is not appended to the UA header.o On: The MAC address is appended to the UA header.o Default value: Off.

Securecall preference:o This parameter enables media security (secure RTP) if SIP Transport Layer Security (TLS) has

been used for signaling. Secure-call preference is supported from Nokia S60 VoIP

Release 2.1 onward.

o Prefer secure: A secure call is preferred. If the other end does not support security, a fallbackto a nonsecure call takes place.o Prefer nonsecure: A nonsecure call is preferred.o Use secure only: Security is mandatory for mobile originated (MO) call establishment.o Default value: Prefer nonsecure.

Count of VoIP digits:o This parameter defines the meaningful count of caller-ID characters for caller identification. It

is supported from Nokia S60 VoIP Release 2.1 onward.

o 0: All caller-ID characters are meaningful.o 320: Number of meaningful caller-ID characters.o Default value: 0.

Ignoring domain part:o This parameter defines the rule for displaying the domain part of a uniform resource

identifier (URI) for incoming Internet calls in the user interface. It is supported from Nokia S60

VoIP Release 2.1 onward.

o On: The domain part is not displayed if E.164 numbers are used in the user part of the URI.o Numbers only: The domain part is never displayed.o Off: The domain part is displayed.o Default value: Off.

Figure 28: A new codec is added.

To delete a codec, choose the codec to be deleted, and then select Options > Delete.Each codec has its own set of parameters and appropriate values for those parameters. These are

described in the following section.

3.3.1 Adaptive Multi-Rate Narrow Band (AMR-NB) codec parameters Ptime:

o The length of time in milliseconds represented by the media in a packet. The ptime may varybetween the codecs default ptime and maxptime so that the ptime is increased by themultiples of its allowed values. If other allowed values are not mentioned, the default value

and its multiples should be considered as the allowed value.o Default value: 20, indicating a 20-ms speech block in one RTP packet.

Maxptime:o Time in milliseconds; a value in the range of 20200.o The maximum amount of media that can be encapsulated in each packet, expressed as time

in milliseconds. The time shall be calculated as the sum of the time the media in the packet

represents. The time should be a multiple of the frame size. If this parameter is not present,

the sender may encapsulate any number of speech frames into one RTP packet. This attributeis meaningful probably only for audio data, but it may be used with other media types if it

makes sense. It is a media attribute, and it is not dependent on the character set. Note that

this attribute was introduced after RFC 2327, and implementations that have not been

updated will ignore this attribute.o Default value: 200.

Jitter buffer size:o A positive integer (milliseconds) in the range of 20200.o Default value: 200.


16/28

Voice activ. detection:o Enabling of VoIP discontinuous transmission (DTX), so that RTP packets are not sent during

silent periods. AMR generates Silence Description (SID) packets during inactivity, but the

packet frequency is reduced.

o On: Enabled.o Off: Disabled.o Default value: Off.

Octet align:o On: Enabled. Octet-aligned framing used according to RFC 3267.o Off: Disabled. Bandwidth-efficient framing is employed.o Default value: Off.

Maxred:o

Definition of the maximum length of time in milliseconds that elapses between the firsttransmission of a frame and any redundant transmission that the sender will use. This

parameter allows the receiver to have a bounded delay when redundancy is used. The

allowed values are between 0 and 100. If the parameter is omitted, no limitation on the use

of redundancy is present. The value must be a multiple of the used frame time. The parameter

is supported from Nokia S60 VoIP Release 2.2 onward.

o 0: No redundancy will be used.o 20100: The maximum length of time in milliseconds that elapses between the first

transmission of a frame and any redundant transmission that the sender uses.

o Default value: 0. Mode change period:

o Definition of the frame blocks at which codec mode changes are allowed for the sender,which is also known as the frame-block period. The initial phase of the interval is arbitrary,

but changes must be separated by a period of N frame blocks; that is, a value of 2 allows the

sender to change the mode every second frame block. The value of N can be either 1 or 2. If

this parameter is not present, mode changes are allowed at any time during the session, the

equivalent of N=1. The parameter is supported from Nokia S60 VoIP Release 2.2 onward.

o 1: Mode changes are allowed at any time during the session.o 2: Mode changes are allowed every second frame block.

3.3.2 Pulse Code Modulation -law (PCMU) (G.711 -law) codec parameters Ptime:

o The length of time in milliseconds represented by the media in a packet. The ptime may varybetween the codecs default ptime and maxptime so that the ptime is increased by the

multiples of its allowed values. If other allowed values are not mentioned, the default value

and its multiples should be considered as the allowed value.o Default value: 20.

4 NAT FW settingsThe Nokia S60 VoIP implementation has Simple Traversal of User Datagram Protocol (UDP) Through

Network Address Translators (NATs) (STUN) protocol support for NAT traversal and NAT binding-refresh

features. The traversal features of the NAT FW enable the VoIP function behind certain types of NATs.With the SIP VoIP Settings application, the user can also create the STUN settings.

NAT FW settings by default refer to SIP domain-specific settings. Refresh timers are overridden with

IAP-specific NAT FW settings, if IAP-specific values are defined.

To access the NAT FW domain or IAP-specific settings, from the main screen, choose the NAT FW

settings item, and then select Options > Open, as shown in Figure 29, to display the NAT FW settings

screen, as shown in Figure 30.

Figure 29: The main SIP VoIP

Settings screen includes the NAT

FW settings item.

The following parameters are available for determining the NAT FW behavior for a domain:

STUN server name:o Definition of the STUN server address in the domain-specific NAT FW settings. This parameter

is optional. By default, the DNS SRV query tries to find the STUN server.o Use the value 0.0.0.0 to disable the STUN server, if, for example, a Session Border Controller

(SBC) is taking care of the NAT traversal.

o Default value: Not defined. STUN server port:

o A number in the range of 102465535.o Definition of the STUN server port in the domain-specific NAT FW settings. This parameter

is optional.

o Default value: 3478. TCP NAT bind. refresh:

o A number in the range of 09999.o Definition of the NAT-refresh interval for TCP in the domain-specific NAT FW settings. The

refresh interval is defined in seconds. If an IAP-specific value for this interval is defined, it

overrides this value. This parameter is optional.

o Default value: 1200. UDP NAT bind. refresh:

o A number in the range of 09999.o This parameter defines the NAT-refresh interval for UDP in the domain-specific NAT FW

settings. The refresh interval is defined in seconds. If an IAP-specific value for this interval is

defined, it overrides this value. This parameter is optional.

o Default value: 28. CRLF refresh:

o Definition of the use of CRLF-based NAT-binding refresh. It enables CRLF refresh to theoutbound proxy (or to the registrar if no proxy is defined) over any transport. This parameter

is optional, but enabling it is strongly recommended when there is known to be either a NAT

or firewall on the route or when the SIP proxy requires refresh to keep the persistent TCP/TLS

connection alive.
