Hi jenning, I am still not sure about the problem. I have few questions which, if answered, can help in finding the problem. 1. Is there any possibility of INVITE getting dropped because in your case Max-forwards is 5? If INVITE is not reaching till UAS, how r u getting to tag?
2. why contact header has different values in INVITE and BYE? Was there any change in IP address of UAC? Is this related to hotspot? If this is the case then target update request should also be sent to UAS.
