Alright cool so technically in that sense it's not really a VoIP device like MagicJack or Skype but rather "voice over coax"? I am just curious what exactly this thing is ever since switched to from DSL to cable at my business. I was surprised when I learned that not only will we have one modem for internet, but another, huge 18 inch modem attached to the wall in our breaker room, with wires going all over the place. I'm not complaining as all 5 lines plus 2 fax lines work great, I'm just curious what else this can do since it's so new to me. I read in the manual this thing can do internet in addition to telephony. Do you think SL would let me hook up a router to this, giving our business a wider radius of wifi coverage? The single router is downstairs and the second floor doesn't get good reception from downstairs.
