[asterisk-users] Handling multiple fax machines and the fax extension, and general call routing

[arkda]

I'm using two contexts, [internal] and [external] as in the example. There
are four digit extensions for each fax machine in my [external] context (the
[external] context is the context in which my PRI terminates) as well as in
the [internal] context.

I just found that I'm able to 'cheat' slightly. If I capture the ${EXTEN}
into another variable and simply call that in the fax extension like so:

[external]
exten => fax,1,Goto(internal,${FAXER},1)

exten => 1000,1,Answer()
exten => 1000,n,Set(FAXER=${EXTEN})
exten => 1000,n,Wait(3)
exten => 1000,n,Goto(internal,1000,1)

--------------------------------

This appears to redirect the call to the appropriate entry under [internal].
This isn't exactly elegant, but I think it will work. It seems odd to me
that there isn't a better method of routing calls once they've been routed
into a catch-all extension such as 's'.
