Works fine but needed an IT guy to tie the phones into each other to get them to work with the network works fine with Vonage!

The supported CODECs (which now include G.722) default to PCMU, which is working great with our existing asterisk system

User interface is a little clunky but the phone works very well and its substantially cheaper than competing products.

Using it home office use and once I got the phone to sync up my fiber provider the phone worked great
