Hello all, in the given scenario, a CANCEL-message is t_relay()-ed to the next hop user agent in transport UDP, and the target agent does not to it. However, openser is not re-transmitting the cancel message:
# U 2006/05/30 10:35:14.928141 USERAGENT-A:5060 -> OPENSER:5060 CANCEL sip:[EMAIL PROTECTED]:5060;user=phone SIP/2.0.

The second cancel is the only cancel ever that openser will send out. I believe it should start re-transmission of the cancel message after 500ms, then 1000ms etc. Is this a known issue?
