Hi Moises,

Thanks for the reply. I am using a SNOM 320 phone as SIP end point. On being invited, it sends back a SIP/2.0 180 Ringing. How does FreeSWITCH/FreeTDM behave in this case - would it send media as part of the Progress message (in band)? Is there a way for me to check if media is being sent out to the caller?

I think strictly speaking a 180 should not trigger any early media (ring tone). The SIP response code for early media is 183 (although I've heard about 180 sometimes containing SDP).

If ring_ready solves your problem, what problem are you trying to solve now? I am not sure 180 should be triggering any media bridging code.
