[Freeswitch-users] SOLVED Re: No ringback/transfer_ringback freetdm

[NeCoSec - Ulrich Schinz]

Hi again,

I solved my problem. Only, I'm not sure, I understand my solution....

Like written, I'm transferring the call in context default, there is an
extension defined, where ringback was set to ${de-ring}. After
commenting this part, everything works find.

But why?? Anybody has an idea?

Kind regards
Uli
