[Freeswitch-users] intermittent EXCHANGE_ROUTING_ERROR

Hey All, About once or twice a day, I'm getting an EXCHANGE_ROUTING_ERROR failure. I've enabled debugging, including logging SIP messages, and can't seem to find the cause of the error. Freeswitch goes from setting variables to exchange routing error: switch_channel.c:935 EXPORTING[export_vars] to switch_ivr_originate.c:2447 Cannot create outgoing channel of type [sofia] cause: [EXCHANGE_ROUTING_ERROR] Whenever that happens, "switch_channel.c:816 New Channel" is never called and I don't see any outbound SIP messages to the IP in question. So if no new channel is created, how can there be a routing error? Any insight or advice on how to debug this would be greatly appreciated. Thanks!
