Cisco - Refurbished Excellent - ATA192-3PW-K9 Multiplatform 2-Port Analog Telephone Adapter with Router, 2 FXS Ports, SIP, T.38 Fax, Webex Calling - Black

The Cisco ATA192-3PW-K9 Multiplatform Analog Telephone Adapter is a 2-port handset-to-Ethernet adapter that turns traditional analog telephones, fax machines, and overhead paging devices into SIP IP endpoints. Designed for enterprise networks, small offices, and hosted cloud unified communications, the ATA 192 features two RJ-11 FXS ports that can be configured independently as two Session Initiation Protocol registrations, plus two 10/100 Mbps RJ-45 Ethernet ports with an integrated high-performance router for extended local network connectivity. It supports G.711, G.729a, G.729ab, and G.726 codecs, real-time T.38 fax relay, echo cancellation, voice activity detection, and comfort noise generation for clear, natural-sounding calls. The ATA 192 works with Cisco Webex Calling, BroadCloud, BroadWorks, Metaswitch, Asterisk, and other third-party SIP call control platforms, with zero-touch cloud provisioning via TR-069, IPv4/IPv6 dual stack, SRTP, SIP over TLS, and a dedicated Problem Reporting Tool button for simplified troubleshooting. An ideal analog-to-VoIP gateway for migrating legacy phones, fax, and paging equipment to modern IP telephony.

• Two FXS Ports for Analog Phones, Fax, and Paging: Connects two standard analog devices, such as telephones, fax machines, or overhead paging systems, to any SIP-based IP telephony network. Each of the two RJ-11 FXS ports can be configured independently as a separate Session Initiation Protocol registration, giving you two fully independent phone lines from a single compact adapter.
• Integrated Router with Two 10/100 Ethernet Ports: Built-in high-performance router with two 100BASE-T RJ-45 Ethernet ports extends local network connectivity, supporting NAT, port forwarding, DMZ mode, DHCP, static and dynamic address assignment, MAC address cloning, and VPN pass-through for IPsec ESP, PPTP, and L2TP. QoS support includes 802.1p/Q VLAN tagging and DiffServ for prioritized voice traffic.
• Works with Webex Calling, BroadWorks, Asterisk SIP: Certified to interoperate with Cisco Webex Calling, BroadCloud, and BroadWorks, and compatible with Metaswitch, Asterisk, and other third-party SIP call control platforms. No license is required to connect the ATA 192 to third-party call control systems, making it a cost-effective plug-and-play gateway for hosted and on-premises voice deployments.
• T.38 Real-Time Fax over IP and G.711 Fax Pass-Through: Supports real-time Group 3 fax over IP using the T.38 fax relay standard for reliable fax transmission across IP networks, with automatic negotiation of transmission rate. G.711 fax pass-through and fax tone detection are also supported. Voice codecs include G.711 a-law and u-law, G.729a, G.729ab, and G.726 with adaptive jitter buffer and echo cancellation.
• Zero-Touch Cloud Provisioning and Advanced Security: Simplifies mass deployment with zero-touch provisioning through TR-069 and XML configuration files, remote cloud configuration, and automated provisioning over HTTP, HTTPS, and TFTP. Built-in security includes SIP over TLS 1.1 and 1.2, Secure RTP encrypted calling, AES encryption, HTTPS with factory-installed client certificate, secure boot, SSH access, and SNMPv3.
