I would like to make a small investment in either a PC-Based or something like the AVAYA Office, VOIP telephone systems.

I have a cable modem service here at the old homestead and I would like to teach myself the next generation of Phone Systems.

Anybody have any suggestions or whoever can guide me to the right vendor, I would be appreciated.

I am interested in learning the programming and diagnostics of VOIP phone calling.

Thankx to all, Mitch
