The information on this page is based on feedback from Enswitch customers using these telephones in production. This list is incomplete, and some entries may be out of date. Any updates are welcome. All information on this page is informal, and no guarantees are offered. As always, it's vital to fully test all functionality before offering it to your customers.

"Working" means that the basic functions of the telephone have been reported as working. "Fully working" means that all or almost all relevant functions of the telephone have been reported as working. Integrics has not verified these for all telephones.
