Extend the investment of your analog communications equipment with this ATA 191 2-Port RJ11-to-Ethernet Multiplatform Analog Telephone Adapter from Cisco. This device features two RJ11 and a single RJ45 port, giving you the ability to connect legacy analog equipment to take advantage of IP telephony applications. It’s designed to work with third-party call-control systems, and is not compatible with Cisco call-control systems.
The two RJ11 FXS ports can be configured independently as two SIP (Session Initiation Protocol) registrations, and offers a variety of features to both enhance voice quality and network compatibility. Built-in audio pre-processing is engineered to offer clear and natural conversations with echo cancellation, voice activity detection, and comfort noise generation. It also enables IPv6 dual stack for migration to more advanced IPv6 protocol networks.
