asterisk users - May 2007 - Urgent: DTMF does not work with, rtpmap:101 telephone-event/8000

Alex thank you for your response. 
In this case we are USING INBAND, though I have tried both. Nothing works. 
Yes ser is configured with mediaproxy. 

Thank you,

JK,

In-band or RFC2833 DTMF signaling?

Also, unless you have SER configured with a media proxy, the actual
"call"
is not running through SER.  It's a signaling proxy only.

   Depending on the exact acoustic qualities of the end-to-end path,
in-band can be problematic.  If you're relying on far-end equipment to
discriminate tones from within an audio stream that is subject to
potential transcoding, mangling, packet loss, out-of-order arrival, etc.,
you may be out of luck.

   Admittedly, I'm not sure exactly what your problem is.  But you're
almost always better off using out-of-band RFC 2833.
