Hi,
I tried to ask this question in sip-implementors maillist but nobody
could answer it there...
What is the proper way to indicate Silence Suppression and Echo
Cancelation coder parameters in SDP? In MGCP these parameters are
passed in LCO element, but for SIP Offer/Answer model these parameters
should be passed in SDP. Right?
There is RFC3108 that defines "ecan" and "silenceSupp" attributes, but it
applies to VoATM. Is it applicable to VoIP too?
Some late drafts, e.g. draft-ietf-sipping-realtimefax-00.txt, seem to assume
RFC3108 attributes are valid for VoIP. Is this correct?
Best regards,
Alex Agranov
