[Freeswitch-users] How to configure ring back for calls through freetdm?

[Antonio Modesto]

Hi,

	I've written a lua script to make calls using freetdm channels, the
problem is that there is not a ringback tone to the calling party, so
it's not possible to know what is going on until the caller party
answers the call. What do I have to do to enable this?


Thanks.
