With SIP over UDP, when packet fragmentation happens, it destroys the SIP packet as UDP does not auto-reassemble the fragments… this happens once your sip packets exceed MTU… the only fix is small packets. That means compact headers, eliminating extra headers, or just don’t use such a big SDP by eliminating CODECs you don’t need.<o:p></o:p></span></p><p class=MsoNormal><span
