A while back, on the SIP-list, I discussed the necessity to indicate packetization size for audo codecs and proposed to include "ptime=" for each codec. See link: http://lists.bell-labs.com/pipermail/sip/2001q2/006521.html Except for several comments questioning the need, there was no comment on my actual proposal. But your Option #2 certainly falls along the same line as my proposal. Regards, Shan Lu Manish S.
