[Freeswitch-users] a=fmtp:101 0-15

[Bilal Dar]

We are having issues sending out DTMF, primarily when dial any conference
bridge.

My provider asked me to send  'a=fmtp:101 0-15' instead of 'a=fmtp:101
0-16'. They do not accept flash.

Appreciate if anyone can let me know how we can fix that.

Thanks

Bilal
