I also got a system installed recently. I think it?s Broadcore Hosted VoIP PBX system. I am pleased with the Customer Service of the company. They are located in south California. I submitted my support ticket last Friday and they called me on the same day. The technician told me my problem was probably the adaptor and that he was sending me a replacement immediately. He also told me he turned on the fax/data capabilities. Then he tested the call waiting feature I had trouble with and got it resolved. He e-mailed me a confirmation that he was sending me another adaptor and that I should send him my old one.
