The Cisco ATA 191 Multiplatform Analog Telephone Adapter 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.
The Cisco ATA 191 Multiplatform Analog Telephone Adapter 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 Cisco ATA 191 Multiplatform Analog Telephone Adapter, 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.
The Cisco ATA 191 Analog Telephone Adapter is designed to work with 3rd party Call Control Systems (e.g., Ring Central, Vonage Business, Nextiva, Webex etc.). Will not work with Cisco Call Control Systems.
