Dear All, I have call flow like where Vendor sends 183 w/SDP included Rseq and customer sents the PRACK and 200 OK from vendor.
After that vendor is again sending 1~2 183 w/SDP where it is not changing anything in SDP but only asking for PRACK by sending RSEQ. I checked the RFC , but cannot see anything like which says UAS cannot send multiple 183 w/SDP. Can you please help on this, whether any UAS can send multiple 183 w/SDP where it is asking for PRACK? Is it valid call flow, because i cannot see anything RFC.
