<DIV><FONT face=Arial size=2>Yes I did, but again, that times out on a progress
message, if you have a dead carrier you are sending the message to, it
waits for the leg timeout which in our case needs to be set to about 12 seconds
to allow for cell phones etc. So it takes quite a while to switch, the
calling party usually hangs up or the call completion time is just to
long.</FONT></DIV>

<BLOCKQUOTE TYPE="CITE"><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></BLOCKQUOTE>
