Hi Team, I have a doubt on client/UE behaviour on the below scenario. Can any please help me share any spec. on what UE behaviour based on the below scenario.
1. MO voice call to User-B 2. 183/180 received from User-B 3. 181 Call Forwarding received from network 4. 183 received from User-C with "PEM header as sendonly" & SDP "a=curr:qos remote none" 5. MO send UPDATE for QOS updation to Network/User-C 6. Network send 200 OK with "audio port as 0" <<<< What should be UE behaviour here i. Should MO send CANCLE to end the call ? <<<<< Please share any spec. reference if this is expected from UE ii. What issue if call does gets continued ? 7. Here network again sending 183 with "valid Audio" port to UE <<<< As per RFC#3264 UE should honor latest SDP received from network 8. MO sent UPDATE and received 200 OK with "valid Audio port" 9. MO received 180 Ringing followed by INIVTE/200 OK/ ACK <<<< Call got connected here 10. Immediately MO sent BYE to network/User-C Questions: 1. Does MO should send CANCLE for 200 OK with audio port 0, ? 2. What is the spec deviation if call gets continued ? 3. If 1 is yes, what should be MO behaviour if received valid audio port again from network before call connected ? Thanks for all of your responses, in advance -- With Regards Arun A.
