File Field Name
Web Parameter Name
Valid Range and Description
The coder name is case-sensitive.
If silence suppression is not defined (for a specific coder),
the value defined by the parameter
EnableSilenceCompression is used.
The value of several fields is hard-coded according to
well-known standards (for example, the payload type of
G.711 U-law is always 0). Other values can be set
dynamically. If no value is specified for a dynamic field, a
default value is assigned. If a value is specified for a hard-
coded field, the value is ignored.
Only the ptime of the first coder in the defined coder list is
declared in INVITE / 200 OK SDP, even if multiple coders
are defined.
If the coder G.729 is selected and silence suppression is
disabled (for this coder), the gateway includes the string
‘annexb=no’ in the SDP of the relevant SIP messages. If
silence suppression is enabled or set to ‘Enable w/o
Adaptations’, ‘annexb=yes’ is included.
Both GSM-FR and MS-GSM coders use Payload Type =
3. Using SDP, it isn’t possible to differentiate between the
two. Therefore, it is highly recommended not to select
both coders simultaneously.
For example:
CoderName = g711Alaw64k,20,,,0
CoderName = g711Ulaw64k,40
CoderName = g7231,90,1,,1
CoderName = g726,$$,2,,0
DSPVersionTemplateNumb
er
[DSP Version Template
Number]
Determines the number of the DSP load. Each load has a different coder
list, a different channel capacity and different supported features.
Available values are 0, 1, 2 and 3.
For detailed information on the supported coders and channel capacity, see
the Release Notes.
VBRCoderHeaderFormat
Defines the format of the RTP header for VBR coders.
0 = Payload only (no header, no TOC, no m-factor) (default).
1 = Supports RFC 2658 - 1 byte for interleaving header (always 0), TOC,
no m-factor.
2 = Payload including TOC only, allow m-factor.
3 = RFC 3558.
