Summary:                    DTMF not reproduced towards ZAP T1 Port after
connection has arrive as SIP Trunk
Description: 
When I dial from a standard telephone set to a DID that's provides SIP
Trunking and the call is routed (bridged SIP to ZAP T1 (TE410P)), I see the
call arriving and setup on ZAP port, but afterwards, any DTMF presses are
ignored.

I use e&m signalling toward ZAP. I hear the asterisk placing the DTMF
properly toward ZAP. Call connects, any further DTMF pressed digits from
SIP Trunk is very short sounding on the ZAP and ignored. ZAP to ZAP
connection are perfect. Version 1.2 this was not an issue as it's working
now.  

I have a test system to demonstrate this behavior.  And I can give you
full access to system to see / test yourself. 

I'm using:
* Asterisk Source Version : 1.4.21 (released)
* Zaptel Source Version : 1.4.11
* Libpri Source Version : 1.4.4
* Addons Source Version : 1.4.7

I'm using PBX in a Flash, but today I made a trixbox install on another
box, and it too has this same behavior - 

Also, I found if I press a single dtmf rapidly 2 out of four might be
heard.
