Subhartha, Banibrata,
The 'X' in the codec definition means it is not well known /
defined standard or similar ? so if in doubt is / would be safer to define
codec properties with the attribute lines to define all properties for
these in the SDP - especially with comments such as those provided by Uzi
Uzi said:
"G.729B added the use of SID frames. Therefore you need to negotiate it. By
default G.729B is assumed
to be supported, and you have to declare that you don't support it if this
is your case. The way to
do it in SDP is by adding
a=fmtp:18 annexb=no"
Regards,
Wayne.
