Ticket #302 changed the behavior of INVITE UAC transaction, it stops INVITE request retransmission as soon as CANCEL is requested, if the INVITE request hasn't been responded with any provisional response.

This turns out to be incorrect. The correct behavior should be:

  1. continue retransmitting INVITE.
  2. when provisional response arrives, send CANCEL
  3. otherwise when INVITE finally times out, return 408
