Hi I am confused about the section 13.2 of RFC 3261. The description given in the RFC looks inconsistent. My call flow is as follows:
INVITE with sdp & Supp 100rel -----------> 100 Trying <------------ 180 Ringing with Req 100rel & sdp <------------ PRACK no sdp ------------> 200OK for prack no sdp <------------ 200OK for INV no sdp <<is this OK>> <------------ ACK -----------> Is the above call flow correct? -------- o If the initial offer is in an INVITE, the answer MUST be in a reliable non-failure message from UAS back to UAC which is correlated to that INVITE. For this specification, that is only the final 2xx response to that INVITE. That same exact answer MAY also be placed in any provisional responses sent prior to the answer. The UAC MUST treat the first session description it receives as the answer, and MUST ignore any session descriptions in subsequent responses to the initial INVITE. ---------- Thanks Harsimran Singh _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
