The Cisco ATA 191 Analog Telephone Adapter (ATA191-3PW-K9) combines modern IP telephony networks with traditional analog telephony equipment in a small, dependable package. Analog phones, fax machines and modems can all function smoothly across SIP-based IP networks with this adapter, which is perfect for companies switching to VoIP or expanding old systems. The Cisco-engineered ATA 191 offers flexible interoperability with third-party IP-PBX systems and Cisco Unified Communications Manager, as well as outstanding call quality and secure signaling. Its plug-and-play design and flexible deployment options, such as Power over Ethernet (PoE), make it the perfect alternative for small offices, branch offices or hospitality settings looking to migrate to VoIP at a reasonable cost without having to replace their current analog equipment. With its wide range of codec support, integrated security features and strong QoS capabilities, the Cisco ATA 191 guarantees a seamless, safe and excellent communication experience that makes the most of your present analog assets for contemporary business requirements.
• Dual FXS Ports connect two analog telephones, fax machines, or modems for simultaneous communication over IP networks.
• SIP Protocol Support that has full compatibility with SIP (Session Initiation Protocol) for seamless integration with Cisco CUCM, BroadSoft or other SIP-enabled IP PBX systems.
• Power over Ethernet (PoE) Enabled with optional PoE support simplifies installation and reduces cable clutter by delivering power and data over a single Ethernet cable.
• High-Quality Voice Codecs supports G.711, G.729AB and G.726 codecs for clear, bandwidth-efficient voice calls.
• Secure Communications includes encryption for signaling (TLS) and media streams (SRTP) to protect against eavesdropping and tampering.
• Flexible Deployment that has a compact form factor with straightforward setup supports both centralized and remote office environments.
• Integrated Quality of Service (QoS) ensures prioritized voice traffic to maintain call clarity and reduce latency or jitter.
• Extensive Fax and Modem Support designed to reliably handle fax transmissions (T.38 and pass-through) and modem communications over IP.
• Web-Based Management Interface with user-friendly configuration and monitoring via HTTP/HTTPS interfaces enable easy administration.
• Robust Interoperability that is tested with a wide range of Cisco and third-party analog devices and IP phone systems for maximum flexibility.
