[Freeswitch-users] Translating DTMF from RFC2833 to INFO

[Yehavi Bourvine]

Hello all,

  *debug voip rtp session named-event*s shows that it receives and
understands the DTMFs, but it does not send them to the PSTN (sends only
those received via INFO). I haveto find some time and go to the remote site
to update to the latest IOS... I will update after this has been done.

                            Regards, __Yehavi:
