Hi,
I do use the first solution based on DIALSTATUS variable. (
http://www.voip-info.org/wiki/view/Superdial+macro)
since it's included to a separated context named [superdial-macro], I don't
have to repeat it over and over, so the fact that it's not a oneliner
doesn't bother me at all :)

Hello list,
I need a hand to find the best dialplan failover solution
when using two SIP Trunks.
My reasons to do failover are:
a) one of the two providers could be unreachable
b) both providers may be UP but one of them could return a SIP error
message (maybe caused by DOWN E1s)
Googling I found a few possible solutions:
1. Using DIALSTATUS variable.
2. Dialing in sequence:
exten = _X.,1,Dial(SIP/${TRUNK1}/${EXTEN})
exten = _X.,2,Dial(SIP/${TRUNK2}/${EXTEN})
3. ChanIsAvail
Using the first method it’s possible to get the CONGESTION
and CHANUNAVAIL status which pretty much solves my problem but it takes more
than 2 lines of dialplan(I like one liners).
The second solution requires less space in the dialplan but it should work
only when the called party is busy (or maybe even when the first trunk is
down).
Is there a clean way to send the call to the second SIP provider if the
first one is unreachable or spits out sip error messages?
Thanks in advance,
Alex
