Cisco ATA191-K9 VoIP Phone Adapter

Cisco ATA191-K9 VoIP Phone Adapter

This analog telephone adapter (ATA) from Cisco, the ATA191-K9, lets you hook up conventional analogue phones, fax machines or modems to IP telephony networks. It comes with two FXS ports, supports SIP and IPv6, and delivers secure voice traffic through TLS and SRTP encryption. It is a good fit for smaller companies or home-based workers who need to bring older equipment into contemporary VoIP setups.

Deployment and administration are made easier thanks to auto-provisioning through TR-069 or XML configuration files. A broad selection of codecs is supported, among them G.711, G.729a and G.722, for high-quality audio. Its compact design and Power over Ethernet (PoE) support mean it can be installed in virtually any workspace without extra power cabling.
