The voicemail service is not working. I have tried using the voicemail guide was provided, however, it is still not connected to the voicemail service. When there is a call coming in, after several rings, it will not divert to the voicemail. Instead, it will continue to ring till time out.
Have tried to upgrade my firmware to CME 7.0 as recommended for the usage of CP-7937, but it is still not working.
I have attached my config list.
Can I have some advices, please?
