My first issue is that when the extension is dialed from the outside, either via auto attendant or by their direct line, the system announces "please hold while I tranfer you to: ** ". There is about 5 seconds of silence after that and the system takes the caller back to the main greeting. If that extension is dialed internally, the voicemail picks up fine.

On a similar note, I have 2 people who lost their offices. We chose to move the station port locations to those desk, to reflect the correct extensions of the new people. However, we still wanted the previous extensions to route the caller to voicemail, so that they could check it by dialing in. This worked for a while, but now is doing the same thing as my above problem. It transfers, and plays the name, but routes it back to the main greeting in instead of voicemail.
