SDP Support in MEGACO

The MEGACO supports the basic SDP, as defined in RFC 2327. It supports
also the SDP-ATM, as defined in RFC 3108. However, the only supported
attributes in the SDP are:
•
SILENCESUPP:VAL
(VAL=on or off) – To turn silence suppression on or off (Defined in
RFC 3108).
• RTPMAP
Used for dynamic payload mapping, to map the number to the coder.
The format is:
a=rtpmap:97 G723/8000/1
Where: 97 is the payload number to be used
•
FMTP
used for dynamic payload mapping, to define coder specific
parameters. The format is:
a=fmtp:97 bitrate=5.3
Where: : 97 is the payload number to be used
