Cisco ATA 192 Multiplatform Analog Telephone Adapter ATA192-3PW-K9

The Cisco ATA 192 Multiplatform (MPP) Analog Telephone Adapter (ATA192-3PW-K9) is a 2-Port FXS SIP VoIP Gateway with an integrated router that connects analog phones, fax machines, and overhead paging systems to modern IP-based networks. Engineered for open SIP compatibility, it supports popular platforms such as Cisco Webex Calling, BroadCloud, BroadWorks, Metaswitch, Asterisk, 3CX, FreePBX, RingCentral, Nextiva, 8x8, Vonage Business, and Ooma Office. This reliable Cisco ATA delivers clear voice quality (MOS >4.0), T.38 fax over IP support, and secure HTTPS/TLS/SRTP provisioning—making it ideal for small businesses, service providers, hospitality, healthcare, and enterprise networks. Compact and energy-efficient, it bridges analog and VoIP seamlessly for today's SIP environments.

Key Features & Benefits

  • 2 FXS Ports (RJ-11): Connect two analog devices such as phones, cordless bases, fax machines, intercoms, or paging systems—each port registers as an independent SIP line
  • Integrated Router with 2 x 10/100 Ethernet Ports: Extends local network connectivity with NAT, port forwarding, DMZ, DHCP, MAC address cloning, and VPN pass-through for IPsec ESP, PPTP, and L2TP
  • Open SIP (MPP): Certified for multiplatform VoIP interoperability—works with most SIP trunks and IP-PBX systems, no license required for third-party call control
  • High Voice Quality: Cisco's DSP architecture ensures clear audio with adaptive jitter buffering, echo cancellation, voice activity detection, and comfort noise generation
  • Fax Over IP: Reliable T.38 fax relay (Group 3) and G.711 pass-through support with fax tone detection and automatic rate negotiation
  • Secure Provisioning: SIP over TLS 1.1/1.2, SRTP encrypted calling, AES encryption, HTTPS with factory-installed client certificate, secure boot, SSH, and SNMPv3
  • Zero-Touch Auto-Provisioning: Remote deployment via TR-069, XML config files, HTTP/HTTPS/TFTP—perfect for IT admins and VoIP providers
  • QoS & VLAN Support: Prioritize voice traffic using 802.1p/Q VLAN tagging and DiffServ/DSCP settings; IPv4/IPv6 dual stack
  • Versatile Applications: Ideal for offices, hotels, hospitals, campuses, elevators, paging systems, and remote work setups

Frequently Asked Questions

  • Is this the Multiplatform (MPP) version?
    Yes. The Cisco ATA 192 MPP supports open SIP for compatibility with third-party VoIP platforms. It does not work with Cisco Unified Communications Manager (CUCM / Call Manager)—CUCM deployments require the enterprise firmware variant.
  • What is the difference between the ATA 191 and ATA 192?
    Both have two FXS ports, but the ATA 192 adds an integrated router with two 10/100 Ethernet ports (WAN + LAN) for extended local network connectivity. The ATA 191 has a single Ethernet port with no routing.
  • What can I connect to the FXS ports?
    Analog phones, cordless phone bases, fax machines, intercoms, and paging devices. Two analog endpoints simultaneously—one per FXS port, each with its own independent SIP registration.
  • Does it support faxing?
    Yes. It includes T.38 fax relay (Group 3) and G.711 pass-through with fax tone detection and automatic transmission rate negotiation for reliable fax-over-IP operation.
  • Is it compatible with my VoIP provider?
    Fully compatible with most SIP services including Cisco Webex Calling, BroadWorks, Asterisk, FreePBX, 3CX, Metaswitch, RingCentral, Nextiva, 8x8, Vonage Business, and Ooma Office.
