Sorry, more clearly my question on the previous post was actaully ringback not ring tone. I noticed our voip system doesn't receive ringback tone on some calls.
CCM 3.33, 1751V router with ISDN voice port.
When I call to some numbers(what we found now is cell phone and some international calls)no ringback heard from the ip phone. The called party can hear the ring. Eventually call can be established if the called party answer the call.Any idea. Thanks
