[Freeswitch-users] DTMF issues

[Yehavi Bourvine]

we have a Cisco-2,811 gateway and also have problems with DTMF. Turnning on
debug on Cisco shows that it recgonise the DTMF but do not pass them along.
Our solution was to set the profile toward that Cisco to INFO instead of
RFC-2833 and this solved this issue.
