[SIPForum-discussion] Issue to use Tag

[Dinesh Rao]

Hi Kareena,

Can you send the log trace of your call.What's the problem u facing in
CANCEL.Below is the basic call flow for Cancelling any request.

UAC ----------------------------> INVITE (fromtag , call ID) UAS / UAC
         <------------------------100 trying
         <------------------------ 180 / 183 (from tag , call ID , to tag)
(INVITE)
         --------------------------> CANCEL (from tag , call ID )
         <------------------------- 200 OK (CANCEL)
         <------------------------- 487 Request Terminated (INVITE)
         --------------------------> ACK

Regards
C.Dinesh
