[Freeswitch-users] FreeTDM and ring_ready

[Siri MM]

Hi Moises,

I am not trying to solve any further problems, but am interested in
understanding this better.

Am I right in saying that SNOM(or any other SIP end point for that matter)
should ideally be sending over 183 for the ringback to be triggered from
FreeSWITCH/FreeTDM, and if that's not the case, ring_ready should be used
to simulate the same?
