[Freeswitch-users] DTMF Problems! In-band detection patchy, rfc2833 not working!

[Michael Collins]

Sidharth,

A mobile phone will always send DTMFs in-band, so you need to be ready for
that scenario. I recommend you add this to your dialplan for inbound calls:

Test various scenarios and make sure they work - call from Skype, from
mobile phone, from a land line, etc. Let us know what happens.
