[Freeswitch-users] DTMF not working in my installation

[Sandro Bordacchini]

 Hi Euan.
I think you should probably check how your softphone sends DTMF (usually
could be in-band, rfc2833 or SIP Info, and you have set FS to work with
rfc2833 dtmf).
Setting liberal-dtmf parameter could be of some help sometimes

Hope it helps.
