Thanks for your reply. I checked the RFC and noticed that it does not limit the codec #s in mline, but nor does it comment on infinite number of codecs support being mandatory.
So could you please let me know whether it is mandatory to support them or not. Because if my SBC is not supporting this then i cannot go and ask them to support this.
