[Asterisk-Users] Double DTMF with tdm card

[Bart Fisher]

My problem is slightly different as there is 2 T1 Ports involved - With a T1 
test set I can clearly hear two tones sent quickly with each outside caller 
press.  I assume one of the tones is the actual audio passing thru the 
connection and the other generated by the T1 card itself.    If I make the 
same test with a TDM400 as input connection and the TE410P port as output 
connection, there is no double dialing. Same results if an inside extension 
is used as input connection.  It only happens if it's a T1 to T1 Bridge...

If it is a regenerated tone from the TE410, it seems there should be some 
option to stop listening for tone touch after connection has been 
established?
