Hi, I'm trying to implement a VOIP call between two endpoints. I'm in a doubt.
Say Alice and Bob are in a call. Now, STEP I Alice puts Bob on hold. i.e. INVITE (RTP-sendonly) Alice -------------------------------------> Bob 200 OK (RTP-recvonly) <------------------------------------ ACK -------------------------------------> STEP II After this Bob puts Alice on hold. i.e. INVITE(RTP-inactive) Alice <-------------------------------------- Bob 200 OK (RTP-inactive) ----------------------------------------> ACK <---------------------------------------- ( If Alice has already put the call on hold, then is Step II possible?? ) After this sequence of signaling, say Alice takes the call off hold i.e. INVITTE(RTP-sendonly) Alice -------------------------------------------> Bob 200 OK (RTP ?????) <-------------------------------------------- My Question is:What should bob send as a reply now? _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
