Dialogic® Diva® SIPcontrol™ Configuration
43
Codec profile:
Select the codec list that you configured under Codec Profiles. If you
do not select a list, an internal default list is used with the following
default priority order:
1. G.711A
2. G.711u
3. G.729, if licensed*
4. GSM-FR*
5. G.726 (16, 24, 32, and 40 kbps)*
6. Comfort Noise
7. T.38, if supported by the used Diva Media Board
8. DTMF via RFC 2833/RFC 4733 (no real codec, but internally
handled as codec)
In calls from SIP to the PSTN, the first codec offered by the peer that
is also in the set of supported and available codecs is selected. This
can be changed by a manual configuration that is not currently
available via the Diva SIPcontrol web interface.
*For Office Communications Server 2007, Office Communications
Server 2007 R2, and Lync Server, G.729, GSM-FR, and G.726 are
disabled by default.
Maximum
channels:
Specifies the number of channels that this SIP peer is able to handle
at the same time. This setting is used by Diva SIPcontrol to distribute
calls in a load-balancing scenario and to avoid speech quality
degradation and/or call failures at the peer due to overload conditions.
Early media
support:
Specifies whether the peer supports early media for calls to the PSTN.
For non-human callers, this option should be disabled.
Reliable
provisional
response:
SIP defines two types of responses, provisional and final. Provisional
responses provide information on the progress of the request
processing and final responses transmit the result of the request
processing.
This parameter specifies whether reliable provisional responses (RFC
3262) should be used. The following values are available:
Disabled: Reliable provisional response is not used.
Optional: Reliable provisional response can be used.
Required: Reliable provisional response is mandatory.
Security
You can configure the following parameters in the Security section when you define or
modify a SIP Peer:
