Hi, How in the world do you get 3CX to work with Vonage? I've been trying to get my company's 3CX up for days now. I received their VOIP unit and have tested both RJ11 ports located on the back of it, they both work. The first RJ11 port is xxx-xxx-4511 and it's our voice line. The second RJ11 port is xxx-xxx-4519 and it's our fax line. We've been using one of those phone sets that you buy at walmart that has 4 handsets with them for the past few days and its a pain. We purchased (4) Cisco 7940IP Phones and they all seem to be working with 3CX. I'm able to call internally but have no idea how to setup out going calls. What I need is for someone to explain to me how to connect my 3CX Server to my Vonage VOIP unit so that I can make and receive calls. Please HELP!!!!
