My callflow is real simple. I'm calling an extension that plays a wav file and I hang up the call, 10 seconds after the start of the call, before the end of the playback. You can see from the wireshark callflow below, that at a call rate of 15 CPS, after 20 seconds, it takes 17 seconds for a call to go from 100 Trying to 200 OK. Do you have any other ideas of what could be holding down my freeswitch ? Brian West sip:brian@freeswitch.org
