SDP Media Codec Profile Table

Applicable contexts

SIP service

The SIP Sentinel SDP Media Codec Profile Table declares the codecs recognised by the SDP comparision function and the equivalence classes to which they belong.

The table is a configurable map of encoding name to charging equivalence class. Sentinel SIP inspects the SDP rtpmap lines to provide the rtpmap encoding name for purposes of looking up the charging equivalence class by encoding name key.

Encoding names with the same equivalence class will be considered equal in terms of charging.


The Sentinel SIP configuration includes:

Parameters Description


the encoding name; typically represented in an rtpmap attribute (for example, G723)


the equivalance class to which this codec belongs (for example, Audio8KHzSingleChannel)


the number of channels for the media attribute encoding (for example, 1)


the clock rate for the media attribute encoding (for example, 8000)
