I have a issue with CME + CUE when forwarding calls to voicemail.
When receive an incoming call from SIP Provider number, the correct phone associated starts ringing. After 10 seconds the phone forwards the call to the CUE voicemail pilot number, but who calling hear ringing endless. Seems that CUE is not able to respond.
I'm sure that the matter is the process of forwarding associated to incoming SIP calls, because I have tried this:
incoming call from PSTN is forwarded correctly to voicemail.
incoming call from SIP directed to CUE voicemail (VM administration number from PSTN) is successful (I can hear Cue asking my ID).
Thank you for help
