The later approach is recomended by 3261. In case of no provisional response a timeout approach is prefered.

Subject: [Sip-implementors] Call Termiantion Prior to Receiving 1xx
Need help on following Scenario:
If User A initiated a call to user B, and user A decides to disconnect the
call before it has received a 1xx response, how should the call termination
proceed??
I can think of these 2 approaches but am not sure which one to follow:
1) The user A cannot send Cancel since 1xx hasn't been received.Hence
decides to clear the call at its side. The terminating side sends a 1xx, 2xx
and user B eventually times out.
2) User A waits for the 1xx from user B and then sends a Cancel to user B or
waits for a transaction timeout of Invite to clear the call.
Would appreciate any inputs on this.
Regards,
Kavita
