Hello,
I have an outgoing dial plan which utilizes FWD for any of our outgoing 800,877,866, etc while, toll and local calls get routed to one of our pots lines.
when we use the pots lines, we use the chanisavail function to choose an available pots line.
for example
exten => _1800NXXXXXX,1,ChanIsAvail(Zap/26&Zap/25)
exten => _1800NXXXXXX,2,Cut(theChannel=AVAILCHAN,,1)
exten => _1800NXXXXXX,3,Dial(${theChannel}/w${EXTEN})
works like a champ
Recently, we have had to stop using FWD because at times the call cannot be processed (due to load?? probably). But there is a voice response indicating the call cannot go through.
Currently, all tollfree calls chew up a pots line.
When this happens, I would like the call to failover to one of the available pots lines.
ChanIsAvail is supposed to work with SIP from what I read, but since FWD answers, the call is complete.
Has anybody confronted this type of configuration with any success? Is it possible? If so, a pointer would be appreciated.
Best Regards Greg
