Why Can't a Vonage 'line' be patched through a PBX?

PBX in a small office environment? I have wired my office's PBX (Panasonic) both when we originally purchased it and when we recently moved to a new location. I had hoped to drop from four CO lines to two, but re-install two Vonage lines. I recently have been told it will not work but without an explanation. Could someone in this forum address this situation? Could my system be modified so that I could run a Vonage line through my PBX? Thank you.

I would question the person who told you that it won't work closely. Vonage adapters simulate ordinary land lines quite well, and I see no reason why it wouldn't work.

Do a search through the forum and you'll find a number of discussions on the subject.

It depends on how your Panasonic system is configured, but if it can accept analog POTS lines, it'll take the Vonage adapters quite happily. Now, if you take a PRI line in, forget it.

rbellrbell,
on your PBX you will need to configure your trunks for loop-start and not ground-start and they should be fine. Don't worry about the polarity as it does not matter on loop-start.

From what I have been told over the years, PBX's like ground-start trunks I believe to have better disconnect supervision so please keep that in mind.

Good luck.
