Hi Johan, The first 183 packet that is received has no SDP in it and has:
Require: 100rel I wish to prevent this from being passed on, but still respond what with a PRACK (since 100rel has been requested). The reason for this is that our system will not work if it first receives a 183 without SDP and then receives a second 183 with SDP. Thank you.
