I bought two of them and I use one. The other is still in the box, unopened. Six lines can be configured for Google Voice, Asterisk/FreePBX/3CX or any SIP provider. HD voice, built-in WiFi. I will also include this label card for setting up fancy feature buttons. (A $3 value!) $130 plus you pay shipping method of your choice. "Better deal than eBay!" PM if interested.
