Phoney Phones

[headsplice]

We use it for intra-office communications (we spend a lot of time talking to each other) and one production facility uses it all by itself. We had to add a couple of cards to our PBX's to get them to work, but once we got the kinks worked out of the firewall and router, they work like a charm.
NOTE: The firewall and router are managed, so we don't actually worry about them.
