## Long description

The Cisco ATA 190 (ATA191-K9) is an analog telephone adaptor that converts traditional handsets and fax machines into IP devices by connecting them to an Ethernet network. It provides two independent RJ-11 voice ports (each with its own telephone number) and a single RJ-45 10/100BASE-T Ethernet port, supporting simultaneous voice calls or fax sessions. The unit supports standard VoIP codecs and protocols and is suitable for integration into enterprise, small-office, and managed-voice service environments.
Advantages
The Cisco ATA 190 preserves existing telephone investments by enabling standard analog phones and fax machines to operate as IP endpoints while using existing Ethernet LAN deployments. It supports simultaneous use of both voice ports and provides cost-effective migration to VoIP. The adapter includes support for common codecs and fax transport methods for reliable voice and fax communication and meets multiple regulatory certifications for deployment in residential and business settings.
Suitable for
Connecting analog telephones to a SIP-based VoIP network
Adding a second telephone line or fax line in small offices or homes
Service providers offering managed VoIP or second-line services
Integrating legacy fax machines using T.38 fax relay

How to use
Connect analog phones or a fax machine to the RJ-11 ports and link the ATA to the local network using the RJ-45 Ethernet port.

Usage recommendations
For best results, place the ATA on a reliable Ethernet connection and configure QoS on the network to prioritize voice traffic. Use T.38 for fax transmissions when supported by the service provider, and verify codec compatibility (G.711 or G.729 variants) between the ATA and the VoIP system.
