[Freeswitch-users] Passthrough DTMF

Hi,

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  
perfectly.

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?

Thanks,

-Noah
