<P><FONT SIZE=2>If you send the SIP call to the remote end which is no longer available (unreachable, etc) and have another Dial statement, it will automatically roll over. I would think this would be just as fast, if not faster, than a script updating a db value you check before each call.<BR>

Doesn't seem to have effect. Probably I should state the problem more<BR>
clearly. Ideally, Asterisk should not attempt SIP if there's no way to<BR>
establish a SIP call. This may include lack of IP connection (ping timeout,<BR>
for example), or no SIP listener on remote side (this would be difficult<BR>
because Asterisk can only use UDP).<BR>
<BR>
My environment does not require remote end point to register, so consulting<BR>
the registry is not an option. (This is perhaps what ChanIsAvail does.)<BR>
<BR>
Any suggestions? I'll go to scripting if no other easy way.<BR>
