I really like the Fusion voicemail, but have two questions:
1. Is there any way to listen to a caller that is leaving a message (screening) the way you can with most answering machines?
No, that would be challenging to implement in any scalable way but would be an awesome feature to support.
2. I would like to be able to turn call forwarding on and off, or change the phone number to forward to from
my phone, but I don't see a way to do it in the Wiki (which is down BTW) info. Do you have to go to the voicemail webpage to change it?
No, this is covered on the wiki (we ran into some bugs in openvz that were, uh, unexpected, leading to some issues with the cluster than handles the wiki, corp and forums) https://wiki.sonic.net/wiki/Category:Fusion_Voice
