Hello all,
I am trying to cancel an INVITE but I can't.
UAC ----------------- SER ----------------- UAS
INVITE ------>
CANCEL ----->
<---------481
When UAS receive the CANCEL, it sends a "481 Call/Transaction does not
exist". UAS must send 200 ok and 487 instead of 481.
How can I solve this problem?
Help me please.
Thank you.
