Cisco ATA 192 2-Port Analog Telephone to Ethernet Adapter

Overview

The Cisco ATA 192 2-Port Analog Telephone to Ethernet Adapter is designed to connect up to two standard analog telephones, fax machines, or paging devices to an IP network. It enables small businesses and remote workers to maintain their existing analog equipment while transitioning to modern VoIP services. With two FXS ports that can register independently with SIP providers, it supports separate phone numbers or extensions, making it practical for setups requiring distinct voice lines such as a dedicated fax or business and home calls.
