Make call with alternate provider if NOANSWER

Question

I have two voip providers, one free an the other paid. The free provider only allows local calls to certain area codes, so I need to fall back to the the paid provider if a call fails. At the moment, I have the following context in my extensions.conf file:

[globals]
; freephoneline.ca
PRIMARY_PROVIDER=fpl
; voip.ms
SECONDARY_PROVIDER=voipms

[local]
exten => _NXXNXXXXXX,1,Set(CALLERID(name)=${OUTGOING_NAME})
exten => _NXXNXXXXXX,n,Dial(SIP/${EXTEN}@${PRIMARY_PROVIDER})
exten => _NXXNXXXXXX,n,Set(CALLERID(num)=${OUTGOING_NUMBER})
exten => _NXXNXXXXXX,n,Dial(SIP/1${EXTEN}@${SECONDARY_PROVIDER})
exten => _NXXNXXXXXX,n,Hangup()

I checked the logs and noticed that the free provider responds with NOANSWER if a call is not allowed (Even though it plays a message). What I want is to:

Try calling the ${PRIMARY_PROVIDER} first.
If NOANSWER is returned by provider (not that the callee did not answer), then call with ${SECONDARY_PROVIDER}

How can I modify my dial plan to get the desired results?

EDIT : The primary provider is freephoneline.ca, and I'm using asterisk v1.8.2.3-2

Including the VOIP server you are using and the version number in the body of your question would be helpful in answering. — Tim Brigham, Jun 01 '12 at 13:09

exten => _NXXNXXXXXX,n,Set(dest=${EXTEN})
exten => _NXXNXXXXXX,n,Dial(SIP/${EXTEN}@${PRIMARY_PROVIDER},20,); 20 is how much to call,in seconds
exten => _NXXNXXXXXX,n,Goto(s-${DIALSTATUS},1)

exten => s-ANSWER,1,Hangup
exten => s-ANSWERED,1,Hangup
exten => s-NOANSWER,1,Goto(dialnext,1)

exten => s-CONGESTION,1,Goto(dialnext,1)

exten =>dialnext,1,Dial(SIP/1${dest}@${SECONDARY_PROVIDER})
exten =>dialnext,n,Hangup()

Thanks for the helpful info, but that did not solve the problem. – Alfero Chingono Jun 06 '12 at 20:15

This answer is technically correct but you need to detect CHANUNAVAIL. http://www.voip-info.org/wiki/view/Asterisk+variable+DIALSTATUS – jfalcon aka Don Fanning Jun 07 '12 at 21:40
2jfalcon user say he need NOANSWER. 2adaptive: please show output of asterisk verbose log. – arheops Jun 09 '12 at 16:01
@arheops doesn't matter what he needs... it's what he gets back from the VSP. – jfalcon aka Don Fanning Jun 11 '12 at 05:51
I haven't tested `CHANUNAVAIL` yet, but your answer was helpful. – Alfero Chingono Jun 12 '12 at 18:52
Yes, @jfalcon was rignt! `CHANUNAVAIL` is what I needed. – Alfero Chingono Jun 13 '12 at 12:18

Here is an example of how I do this with google voice and trunks. With my setup I had to make a way to limit gv to 1 channel, also setup a rotation so the first gv trunk is not always hammered since it is first. There is a lot more to this but for just displaying failover I thought this was more than enough:

exten => _1NXXNXXXXXX,n,GotoIf($["${DIALSTATUS}" = ""]?15:)


exten => _1NXXNXXXXXX,15,Set(goto=$[${PRIORITY} + 15])
exten => _1NXXNXXXXXX,n,Set(thetrunk=feliciesmaty)
exten => _1NXXNXXXXXX,n,GotoIf($[${${thetrunk}}  > 0]?${goto})
exten => _1NXXNXXXXXX,n,Set(GLOBAL(${thetrunk})=1)
exten => _1NXXNXXXXXX,n,Dial(Motif/feliciesmaty@gmail.com/${EXTEN}@voice.google.com,,r)
exten => _1NXXNXXXXXX,n,Set(GLOBAL(${thetrunk})=0)
exten => _1NXXNXXXXXX,n,Verbose(0, getting staus ${DIALSTATUS} );
exten => _1NXXNXXXXXX,n,GotoIf($["${DIALSTATUS}" = "SUCCESS"]?hangup:)
exten => _1NXXNXXXXXX,n,GotoIf($["${DIALSTATUS}" = "FAILED"]?${goto}:)
