Enable qualify on your SIP peers. Then configure your outbound dialplan
like this:<br>
<br>
exten => outboundexten,1,Dial(SIP/...)<br>
exten => outboundexten,n,Dial(DAHDI/...)<br>
<br>
If the SIP is up, the call goes through on that Dial statement. When the
call is over and the people hangup, it will not continue down to the next
line. If it's down (and the system knows this because of qualify), it
will fail and automatically roll to the next line. I've used this to
setup failover between DAHDI and SIP a few times.<br>
