Working on new construction for client who also has homes in Aspen and in Cabo. They want to receive voicemail from all three homes into common box, and would be happy if they could all be converted to email. Anyone done this?

The Cabo house has Vonage, which they love and want to expand to other houses. I argued that a hard-wired line is required at each house for alarm, DirectV connection etc - which they agree.

Also desiring to view live/recorded cctv of each home, which is just a DVR IP; not terribly relevant to the above, but thought I would include in the conversation.

I have been selling Panasonic KX-T since the 80s and currently sell nothing but TDA. But I don't do commercial, and frankly have not been keeping up with much of the telecom stuff. Could use some advice please.

Thanks,
Bill
