Vonage. If you're a business and you want these fucking things hooked up coming off of single line telephones. DON'T. CALL. ME. I hate hooking those fucking things up. I wasted two hours of my life today trying to figure out why I wasn't getting any dialtone from this company's second vonage box. Turns out... there was no dialtone. Probably should have been the first thing I checked, but wtf... all the other 10 boxes I've hooked up worked perfectly, including the one I did that morning. All I should have had to do was run a phone line with two simple RJ11 plugs on it from the back of the router to the phone jack, and then snip the wires coming from the Verizon Dmarc. That completed... and still nothing. [/work rant] Now if you have a digital phone system and your network is in the same room... not a problem!!! 10 minutes, 2 six foot cat5 cables, 4 RJ11 plugs later, I'm done! I wish they could all be that easy. disclaimer: if i misspelled anything, shutup. I'm not wearing my glasses.
