Cisco ATA 191 Analog Telephone Adapter (ATA)

The Cisco ATA191 turns traditional telephone, fax, and overhead paging communications devices into IP devices for greater cost-effectiveness. Customers can take advantage of IP telephony applications by connecting their analog devices to Cisco analog telephone adapters.


Cisco ATA191 Key Features

  • Enables high-quality VoIP service with a comprehensive feature set through a broadband internet connection
  • Provides a complete security solution for both media and signaling
  • Offers clear, natural-sounding voice quality via advanced processing, high-performance echo cancellation, voice activity detection and comfort noise generation
  • Improves servicability with a dedicated PRT button for problem reporting and log collection
  • Enables IPv6 dual stack to help migration to IPv6
  • Enables zero-touch provisioning via TR-069 and XML configuration files
  • 2 x RJ-11 FXS ports
  • 1 x 10/100 Mbps RJ-45 Ethernet Port
  • LED Indicators: power, network, phone 1, phone 2 and PRT
  • Wall mountable

The Cisco ATA191 is the preferred solution to address the needs of customers who connect to enterprise networks, small offices, or the emerging unified communications as a service from the cloud. It has two standard FXS ports, which can be configured independently as two Session Initiation Protocol (SIP) registrations. With the ATA 191, customers can protect and extend their existing investment in analog systems, as well as smooth their migration to pure voice over IP in an affordable and reliable way.
