AudioCodes Mediant 1000B - Supported Audio Coders

Version 7.2 417 Mediant 1000B Gateway & E-SBC
User's Manual 20. Coders and Profiles
Parameter Description
Payload Type
payload-type
[AudioCoders_PayloadType]
Defines the payload type if the payload type (i.e., format of the
RTP payload) for the coder is dynamic. For payload types, see
''Supported Audio Coders'' on page 417.
Note: GSM-FR and MS-GSM coders use Payload Type 3. When
using SDP, it is not possible to differentiate between the two.
Thus, it is recommended to configure only one of these coders in
the table.
Silence Suppression
silence-suppression
[AudioCoders_Sce]
Enables silence suppression for the coder.
 [0] Disable (Default)
 [1] Enable
 [2] Enable w/o Adaptation
Note:
 Option [2] Enable w/o Adaptation is applicable only to G.729.
 If you disable silence suppression for G.729, the device
includes 'annexb=no' in the SDP of the relevant SIP
messages. If you enable silence suppression, 'annexb=yes' is
included. An exception is when the remote gateway is Cisco
equipment (IsCiscoSCEMode).
Coder Specific
coder-specific
[AudioCoders_CoderSpecific]
Defines additional settings specific to the coder.
Note: Currently, the parameter is reserved for future use.
