<DIV><FONT face=Arial 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.

<DIV><FONT face=Arial size=2>The tcap trace below shows a typical call to a cell
in our area, the trying is almost immediate while the cell in this case
took 5.5 seconds. I have seen this quite frequently take as long as 12
seconds.</FONT></DIV>

are quite common.</FONT></DIV>
