I have an IP Office R11.0.4.5 with an UC Module V2 R11.0.4.5 that when it's gone through and completed it's bootup process, the Voice Mail will answer for around 5 minutes, but then stops responding and shows unavailable. The System Status show the UC Module is operational and the Voice Mail Services on the Module show Started and running. We have rebooted the IP Office and still not answering. We re-downloaded the C110 iso imaging file again on another thumb drive and re-initialized the UC Module and again, worked for around 5 minutes and then shows unavailable. Are there any suggestions besides RMA on the UC Module? or are we missing something. We can also log into the VM Pro via the VM Pro Client and gain access to it. (Haven't tried building any of the AA's yet to try and see if they would work, since don't want to spend a lot of time doing something that might have to all get redone again if we have to replace the module.
