Problems with dialplan failover

[perlmutr]

NOTE Thruout the post I have changed @ to % because while posting I kept saying too many URL's and would not allow me to post

I have 3 sip carriers. I round robin calls thru the 3 and when a call fails I want to try it on the other carriers.

My dialplan is as follows:

exten => _1NXXNXXXXXX,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _1NXXNXXXXXX,n,GotoIf($[${sip_provider} = 2]?10)

Looking at a call which failed, i see the following in the carrier log:

UNIQUE ID | CALL DATE | SERVER IP | LEAD ID | HANGUP CAUSE | DIAL STATUS | CHANNEL | DIAL TIME | ANSWERED TIME | SIP CODE | SIP HANGUP REASON | PHONE NUMBER |
+----------------------+---------------------+-----------------+-----------+--------------+-------------+------------------------------------------+-----------+---------------+----------+--------------------------------+--------------+

From my server console I see the following:

It tried the call thru the first carrier and never tried the failover.

with other errors such as 503 return is does try the other carriers.

Is there any way for me to capture the no routes available status and try the other carriers

When calls "fail" you don't need to "gotoif". Just dial with the next carrier instead. If the call failed, it'll call the next carrier. If the call is answered, it'll be removed from this diaplan entirely and the next lines won't execute.
