The Cisco ATA190 is a compact desktop Analog Telephone Adapter (ATA) that connects legacy analog telephone systems to modern IP networks without requiring rack-mount installation or specialized hardware integration. This standalone unit bridges traditional telephony infrastructure with cloud and premise-based VoIP platforms, making it an essential tool for network engineers and IT procurement teams managing heterogeneous communication environments.

The ATA190 features 2 analog FXS ports for connecting standard telephone handsets or fax machines, paired with a single 10/100 BASE-T Ethernet interface for network connectivity. Cisco has engineered this adapter to support enterprise-grade voice quality through HD Voice capability with G.722 wideband codec support, complemented by G.711a, G.711u, and G.729a compression codecs for flexible bandwidth optimization. The device implements SIP signalling and integrates seamlessly with Cisco Unified Communications Manager (UCM) and Webex Calling platforms. Advanced voice processing includes G.168-compliant echo cancellation, Voice Activity Detection (VAD), and Comfort Noise Generation (CNG) for clear, natural conversations. The ATA190 supports multiple DTMF signalling methods—in-band, out-of-band (RFC 2833), and SIP INFO—ensuring compatibility across diverse call control systems. Remote provisioning is enabled through Cisco UCM TFTP and Webex Calling cloud provisioning, with centralized management via web-based GUI. The included external AC power adapter supplies all necessary power; note that PoE is not supported. Operating range extends from 0°C to 40°C, supporting stable deployment across standard enterprise environments.

Typical Deployment Scenarios

• Extending analog phone system compatibility into Webex Calling and Cisco UCM unified communications frameworks
• Integrating fax machines and legacy telephone equipment into modern SIP-based networks
• Providing cost-effective analog-to-IP migration for multi-site enterprises
• Supporting branch office telephony where existing analog infrastructure remains in place
• Enabling remote provisioning and centralized voice management across distributed locations
