When I call from the CCM IP phone, I don't have ringback but if I can from the CME phone I have no problem. I had tried to play around with the service parameter in CCM such as H225 user/H225 progress IE with no luck.
BTW, ip phone to ip phone calls within CCM or CME work fine.
Re: No ringback tone when CCM phone calls CME phone
Thanks Mike. The CME is registered with GK and I don't have a inbound voip dialpeer for calls coming from CCM. In CME, I translated the incoming digits to extension and dialplan-pattern in CME will take care of it. I am thinking there are 2 places that can potentially generate ringback tone, CCM or CME. Didn't had that before with the same configs.
