<FONT SIZE="2">I wonder if anyone has any thoughts on this. Using continue on fail works fine for failover but to the best of my knowledge it only works if you do not get an answer or session progress. The trouble with this is if you are calling cell phones etc, it can take up to 12 seconds to get the messages. I would like to explore if failover could be instituted by not receiving a Trying message. This is usually returned immediately and does stop the freeswitch from sending more invites. That way, a 4 second timer could be used and switch to an alternate route early and still give reasonable completion times. </FONT>
