Can't leave voicemail with Poly VVX 250
I have the phone assigned. I can make outgoing calls. I recorded an outgoing message. When I call the phone, it rings, and I can answer it. However, if I don't answer, it does not go to voicemail, and the caller gets "call failed". I have both user and admin guides, but I don't speak admin. We only have one phone, with wifi, and a Pro account, so can't talk to anyone. It took hours just to get this far. Can anyone help?
