A Canadian Company, Mar Communications Ltd. is producing USA made Handset Telephone products in Tennessee. These Wireless Phones which “originated in Atlanta’s technology corridor”, were designed for commercial and home use with your personal information protection in mind.
If you are looking for a Cordless Phone system that has upgradable driven software and is snoop proof, you may wish to use the phones many US banks and law offices use.
Their secure Wireless Phone products are patented here in the US and the technology is used by large US corporations (AT&T, UPS and others) and the US Air Force; in order to keep confidential information from being intercepted.
Mar Communications also manufactures in California Business Phone Systems, you can put your clients on hold and the system will play a company informational announcement, or music from any radio or prerecorded player (CD and tape player, or even an MP3 player).
Note: Mar Communications manufactures products that are not US made, always verify where the products you wish to purchase are made.
