asterisk users - Jun 2005 - Dial timeout when server down

Hello,

When dialing somewhere and the other side is down, Asterisk waits until 
dial timeout before sending "CHANUNAVAIL". I think that if after
several
seconds there are not any reply (I mean at the IP level) we could 
consider that the link is just down and handle the situation.

Is it possible to configure Asterisk to have this behaviour?

Many thanks.

Yves.

If you're refering to an IAX channel then, yes, that's the concept
behind the 'qualify=' option. However, there are known weaknesses
including that the loss of a single ping makes the remote host appear to be
down. There is a patch for head available at
http://bugs.digium.com/view.php?id=4192 that attempts to make peer qualification
more useful.

Hope that helps.
