Fast Semiconductor has had experience with the Panasonic product for years. He has an an analog system in his house and one in the business. When he was ready to expand, he called and inquired about the NS 700. I did a demo of the system using some remote phones from other locations. He could see the benefits of the remote, as well as the easy migration to the new system. He also was paying a lot of money on phone bills. That cost was cut substantially, enough that the 0% lease payment and the SIP trunks we less than he was paying for dial tone alone. We set up the new system on the analog trunks and ported to the SIP trunks seamlessly.
