We are occasionally running into a situation where our IP Header TTL expires in transit for RTP streams. It has been our observation that our SBC B2BUA that anchors media is not resetting the TTL on RTP packets but is on SIP packets. Is there a standard expected behavior for how SBC B2BUA with media anchoring might handle RTP packets? I would have thought if it resets the SIP packet TTL it would also reset the RTP packet TTL. Thoughts?
