[asterisk-users] IAX2: Calls answered before extension is tested?

[Alan Lord]

[Sorry if this arrives more than once. I have sent this twice and it 
never arrived, despite other messages getting to the list O.K.]
-----------

Hello,

I would like an incoming caller to be able to choose from the menu 
options in my extension.conf below. Once They have dialled the 
appropriate digit, * should call two extensions simultaneously: one SIP 
phone on this * server, and one over a working IAX2 link. If either 
party answers, great. If neither party answers or both are 
busy/unavailable go to relevant voicemail box.

This *almost* works... ;-)

The issue is the call that goes down the IAX2 channel always seems to 
get answered, then cleared down almost straight away. It looks like the 
remote * server is accepting the incoming call sending a connected 
message back, thereby completing the Macro, and only *then* checking if 
the extension is actually available.

Here's the last bit of the log (I've edited the IP address) - we are 
both deliberately NOT answering our phones...

And here's the relevant bits of my extension.conf

exten => s,1,Dial(${ARG1},10,tr)
exten => s,n,Goto(s-${DIALSTATUS},1)
exten => s-NOANSWER,1,Voicemail(${ARG2}@business,u) ; business is the 
voicemail context, ${ARG2} is the context from which this call came
exten => s-BUSY,1,Voicemail(${ARG2}@business,b)
exten => _s-.,1,Goto(s-NOANSWER,1)

==============================

Can anyone see where the problem is? Or suggest a better way?

Many thanks.
