AudioCodes Mediant 500L - Supported Audio Coders

Version 7.2 431 Mediant 500L Gateway & E-SBC
User's Manual 20. Coders and Profiles
Parameter Description
[AudioCoders_rate]
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 431.
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.
Currently, the parameter is applicable only to the AMR coder and
is used to configure the payload format type.
 [0] 0 = Bandwidth Efficient
 [1] 1 = Octet Aligned (default)
Note: The AMR payload type can be configured globally using
the AmrOctetAlignedEnable parameter. However, the Coder
Group configuration overrides the global parameter.
