[Asterisk-Users] DTMF in outbound calls

[Rod Bacon]

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.

Does anyone have any ideas?
