Epygi Quadro4Li IP Phone Expansion Key

The Quadro4Li IP phone key enables up to eight (8) additional local IP phone extensions on the Quadro4Li model bringing the system to 18 total IP extensions. These IP extensions are only available when the Quadro4Li is configured as an IP PBX and not in Key System mode. Key System mode is still limited to a total of 10 IP phone extensions.
