[Asterisk-Dev] Zaptel DTMF Problem?

[Rod Bacon]

I posted this on Asterisk users and got no response. I'm thinking that 
it may be a Zaptel driver issue, but I'm not a programmer so I can't 
simply look in the code and see. Hoping that someone on this list can 
enlighten me.

I have an application that creates a call file and drops it into the
/var/spool/asterisk/outgoing directory. This file places a call and
presents a menu to the called party.

This works perfectly over SIP phones but will not work via my ISDN PRI
(Digium TE410P).

If I dial IN to the menu, DTMF is detected but if Asterisk originates
the call, DTMF is not recognised.
