asterisk users - Nov 2005 - Double DTMF sent on T1 to T1 Native Bridge

I have asterisk sitting in the middle with Telco on one side and Legacy PBX 
on the other using two T1 ports on a TE410P.  I also have the latest Beta 2 
installed.

My problem is after a call is connected (port to port T1) and the outside 
user presses a touch tone, asterisk is repeating the digit.  So if I press 
"1234" the PBX hears "11223344" - really messes up accessing
the voice mail
on PBX.  If I dial into PBX from an internal phone it works correctly.  This 
is a new problem since my upgrade from Asterisk 1.0.9, so I guess there is 
some keyword to disable this feature zapata?

An update:

If I dial with an internal single FXS phone or inbound to TDM400 (FXO) it 
works correctly.
It appears that the Telco T1 is regenerating the DTMF as received at the 
same time the audio DTMF is past though the bridged connection. So, the 
effect is I hear two tones on Legacy PBX connection. - Make sense?

This is a new problem since Asterisk 1.0.9, so I guess it's a bug?

Seems there should be some way to make the Telco T1 stop listening and 
sending DTMF after connection
