Turning traditional devices into IP devices.

This bestseller for analogue-to-digital conversion turns traditional telephone, fax, and overhead paging communications devices into IP devices for greater cost-effectiveness and modern telephony.

Excellent voice quality. For enterprise-level communication.

The Cisco ATA 191 offers a clear, natural-sounding voice quality thanks to advanced preprocessing, high-performance echo cancellation, voice activity detection, and comfort noise generation for an excellent telephony experience. 

A device that meets your needs. Offering flexibility and configuration.

Two standard FXS ports can be configured independently as two SIP registrations. Easily protect and extend existing investment in analog systems - or smooth your migration to pure VoIP in a more affordable and reliable way.
