Good news! Been away from the computer for a while, so wasn't able to
keep up with your efforts.

You're welcome. Glad to have provided some pointers.

Actually, if Read() works, then WaitExten should have worked too. I expect
what was missing was the Answer(). So this ought to work as an alternative:

[from-nec]
exten => s,1,Answer()
exten => s,n,Set(TIMEOUT(digit)=2)
exten => s,n,Set(TIMEOUT(response)=5)
exten => s,n,WaitExten()
exten => _X.,1,Dial(DAHDI/g2/${EXTEN},,Tr)

This would allow you to match different patters to route to different
destinations (e.g. some calls to VoIP or to internal functions such as
conferencing).

Also, there is one improvement I think might be made to either, and that
is to replace the 'r' flag (always generate ringing) with a call to
Progress() before the Dial:

exten => _X.,1,Progress()
exten => _X.,n,Dial(DAHDI/g2/${EXTEN},,T)

or similarly for your Read() solution. Unless I've missed something, that
ought to allow your callers to hear proper busy tones if the call is busy,
or ringing tone if it rings. It might even be possible to put Progress()
before WaitExten() to avoid duplicating it in different dial patterns.

Cheers
Tony
