[Freeswitch-users] Passthrough DTMF

Weird situation.

I am now running my office phone through freeswitch. It works great!

Most of the companies that I call have an IVR that requires a  
keypress:  "for sales press 1, for support press 2, etc."

With most of these calls, my key presses pass the DTMF through  

The odd part is that some of the place I call, my DTMF presses have no  
effect.  I can hear the "tone", but the receiving party does not seem  
to catch it.  I tried repeating the call from a landline and it DID  
receive my DTMF.  This appears to indicate that the way I'm passing  
through DTMF works for MOST carriers/receivers, but not for all.

Is there something I can set in the config to ensure that the DTMF  
will pass through correctly in all circumstances?
