Table 6-7: SIP Configuration Parameters
ini File Field Name
Web Parameter Name
Valid Range and Description
SASRegistrationTime
Determines the Expires header value that is returned in a 200 OK
response to an incoming REGISTER message when in SAS
'Emergency Mode'.
The valid range is 10 to 2,000,000. The default value is 20.
Profile Parameters
CoderName
Defines the gateway's coder list ('Coders' table in the Embedded Web
Server -- refer to 'Coders' on page 96), including up to 5 groups of
coders (consisting of up to five coders per group) that can be
associated with IP or Tel profiles ('Coder Group Settings' screen in the
Embedded Web Server -- refer to 'Coder Group Settings' on page 133).
The first group of coders (indices 0 through 4) is the default coder list
and default coder group.
[CoderName]
FORMAT CoderName_Index = CoderName_Type,
CoderName_PacketInterval, CoderName_rate,
CoderName_PayloadType, CoderName_Sce;
[\CoderName]
Where,
Type = Coder name
PacketInterval = Packetization time
Rate = Packetization rate
PayloadType = Payload type
Sce = Silence suppression mode
For example:
[CoderName]
CoderName 0 = g711Alaw64k, 20,,,0;
CoderName 1 = g726, $$, 3, 38, 0;
CoderName 2 = g729, 40, 255, 255, 1;
[\CoderName]
Notes:
 For a description of using ini file parameter tables, refer to 'Structure
of ini File Parameter Tables' on page 269.
 The coder name is case-sensitive.
 For a list of supported coders, refer to 'Coders' on page 96.
 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 common
standards (e.g., 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 enabled
(for this coder), the gateway includes the string 'annexb=no' in the
SDP of the relevant SIP messages. If silence suppression is set to
'Enable w/o Adaptations', 'annexb=yes' is included. An exception is
when the remote gateway is a Cisco device (IsCiscoSCEMode).
