[Freeswitch-users] Translating DTMF from RFC2833 to INFO

  I have Polycom phones which send only RFC-2833 (or inband which I dislike)
and they should go out to the PSTN via a Cisco gateway. The Cisco gateway
has some bug and accepts only INFO.

I did a few tests:

   - Some of the phones are on different profile than the Cisco. On their
   profile I set 'dtmf-type=rfc2833' and on the Cisco's profile I set
   'dtmf-type=info' and Freeswitch did the translation. All works ok...
   - Some of the phones are on the same profile as the Cisco, so I must set
   dtmf-type to rfc2833; it works with internal applications (like voicemail)
   but does not work through the Cisco as it misinterprets the rfc2833

Is there a way to set some variable (or a parameter to the bridge
application) to do the translation?

                             Thanks! __Yehavi:
