Description: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.

After a caller is connected (port to port T1) and if the outside
Caller presses a touch tone, asterisk is repeating the digits.  

Example: If I press "1234" the PBX hears "11223344"

If I dial with an internal single FXS phone or TDM400 FXO it works correctly.  
It appears that the Telco T1 is regenerating the DTMF at the same time the audio DTMF is past though the bridged connection.

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