HI All,
I have a query regarding Cancelling a call before Provisional response.
As per RFC 3261, CANCEL can be sent after a provisional response (1xx
response other than 100) receivecd. Suppose i make a call
steps:
1) INIVITE sent to Callee
2) Callee didn't send anything
Now i want to cancell the call.
What shold be call flow ?
Thanks,
Anjan
