More info

The Cisco ATA products are standards-based communication devices that deliver true, next-generation voice-over-IP (VoIP) terminations to businesses and residences worldwide. The Cisco ATA 190:

  • Protects existing telephone investment: The Cisco ATA 190 supports two voice ports (RJ-11 phone ports), each with its own independent telephone number, and a single RJ-45 10/100 BASE-T Ethernet port. Each port supports either voice calls or fax sessions, and both ports can be used simultaneously. This adaptor can use existing Ethernet LAN deployments.
  • Is cost-effective: The Cisco ATA 190 helps customers turn their analog phone devices into IP devices cost-effectively and is the preferred solution to address the needs of customers who connect to enterprise networks, small-office environments, or the emerging VoIP managed voice services and local services market

Enterprise customers can use the Cisco ATA 190 to connect analog phones and fax machines to their VoIP network. Service providers are taking advantage of emerging telephony applications and the ease of deploying second-line services using the Cisco ATA solutions.



Configuration and Provisioning

  Configuration as per Cisco endpoints devices
  Autoprovisioning with Trivial File Transfer Protocol (TFTP) for servers
  Automatic assignment of IP address, network routing IP, and subnet mask using Dynamic Host Configuration Protocol (DHCP)
  Touch-tone telephone keypad configuration with voice prompt
  Administration password to protect configuration and access
  Remote upgrades through network
  Cisco Unified Communications Manager (UCM) standard configuration and provisioning options
  Ease of administration

Voice Quality

  Advanced preprocessing to optimize full-duplex voice compression
  High-performance line-echo cancellation to eliminate noise and echo
  Voice activity detection (VAD) and comfort noise generation (CNG) to save bandwidth by delivering voice, not silence; VAD is configurable, and the ATA 190 determines whether CNG should be turned on dynamically
  Dynamic network monitoring to reduce jitter artifacts such as packet loss

Clear, natural-sounding voice quality

Signaling Protocol

  Session Initiation Protocol (SIP) on the Cisco line side

Allows interoperation with Cisco UCM SIP solution


  Secure Real-Time Transfer Protocol (SRTP) and Transport Layer Security (TLS) over SIP

Secure media and secure signaling support, for secure solutions

Fax Support

  T38 fax support

Standard fax capability to send faxes over the IP network; the T.38 fax relay feature enables devices to use fax machines to send files over the IP network

Form Factor

  Fits in most environments

New form-factor design based on the Cisco endpoints portfolio

Cisco UCM Version Compatibility

The Cisco ATA 190 is compatible with Cisco UCM Versions 8.5(1), 8.6(2), 9.1(2), 10.0(1) and later.
