Hi,
Does your proxy set timer for provisional response?
If yes , the proxy will send Cancel after timer expire and responded back 200 OK. Then initial INVITE transaction will be terminated by 487 back from UAS.

Subject: [SIPForum-discussion] In which scenario Proxy will generate CANCEL ?
Hi All
I came across a scenario to test CANCEL which should be generated by Proxy.
In the following scenarios, which scenario is valid?
1 UAC sends INVITE to Proxy, proxy forwards the request to UAS.
Now UAS responds with 180 ringing only but no final response , so in this case Proxy sends CANCEL to UAS or which response ?
Now the proxy sends 408 or 480 to UAC ?
Or in the above scenario is valid only for Forking scenario only, where Proxy tries to multiple locations?
I am confused about the functionality.
Pl give your valuable suggestions.
Regards
Sesh
