Ringback tone on SIP

[Todd]

Are you dialing directly from the phone or a desktop such as GAD?  We've ran into an issue with GAD where we wouldn't hear ringback when making a call from GAD but we would hear it when dialing from the hard phone.  We had refer turned off.  Once that was turned on, it worked fine.

I am talking about inbound calls,outbound calls are different case.

Kubig, check urs options give_treatment and compat_treatments. it depends on environment, i turned it off. and sip-ring-tone-mode=1 is relevant as well.

Thx,but no success. I am afraid that the ring-back tone on SIP server is not possible yet
