Description

The ATA 191 is a 2-port FXS analog telephone adapter from the Cisco ATA 190 Series. It connects analog phones, fax machines and overhead paging devices to an IP network, so existing analog equipment can stay in service while a site moves to VoIP. This ATA191-K9 is the on-premises variant, built for Cisco call control with Cisco Unified Communications Manager (CUCM) and Cisco Unified Communications Manager Express (CME).

The two RJ11 FXS ports can each carry an independent SIP registration, and a single 10/100 Mbps RJ-45 port provides the network connection. Voice codecs are G.711 a-law and mu-law plus G.729a and G.729ab, with T.38 fax relay and G.711 fax pass-through for Group 3 fax. The unit runs from a 5V DC external power adapter at 5 W consumption, supports IPv4 and IPv6 dual stack, and is wall mountable in a compact 100 x 100 x 28 mm housing.

On CUCM, licensing is one Essential User Connect License per port. A spare power adapter, ATA191-PWR, is available separately. The multiplatform firmware variant for third-party SIP platforms is a different SKU.
