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

[Sidharth Kshatriya]

Thanks for your tips Bob.

So I have done the following
1. Used start_dtmf before my lua IVR script starts
2. Asked my VOIP carrier to send me INFO events

Now I need to know what I need to do on my internal and external SIP
profiles in terms of config (if anything, from the default config).
Currently when I get a call on an external line I simply bridge it to my
internal IVR number.

Thanks,

Sidharth
