Hello, I'm trying to get this new system up, but I am having some serious issue with trying to get the voicemail to work. Currently all the function that we're using are working, including voicemail when internal users is calling the local extension number. For some reason though, when I tried calling from my cell phone to the external did number, the voicemail forwarding failed. The log just said call(16) terminated without trying to forward the call... Any reason why this is happening ??
