Cisco ATA 186
The Cisco ATA 186 Analog Telephone Adaptor functions as an analog telephone adapter that interfaces regular analog telephones to IP-based telephony networks. The Cisco ATA 186 converts any regular analog telephone into an Internet telephone. Customers install the Cisco ATA 186 at their premises. Each adapter supports two voice ports, each with its own telephone number.

Connecting with Cisco CallManager
Like other IP devices, the Cisco ATA 186 receives its configuration file and list of Cisco CallManagers from the TFTP server. If the TFTP server does not have a configuration file, the Cisco ATA 186 uses the TFTP server name or IP address and port number as the primary Cisco CallManager name or IP address and port number.
After the Cisco ATA 186 initializes, both ports on the Cisco ATA 186 (skinny clients) attempt to connect with the primary Cisco CallManager. If the connection or registration fails, the Cisco ATA skinny clients attempt to register with the next Cisco CallManager in the Cisco CallManager list. If that connection fails, the Cisco ATA skinny clients attempt to register with the last Cisco CallManager in the list. If all attempts to connect and register with a Cisco CallManager fail, the client attempts to connect at a later time.
Upon successful registration, the Cisco ATA client requests the Cisco CallManager software version, current time and date, line status, and call forward status from the Cisco CallManager. If the Cisco ATA loses connection to the active Cisco CallManager, it attempts to connect to a backup Cisco CallManager in the Cisco CallManager list. When the primary Cisco CallManager comes back online, the Cisco ATA attempts to reconnect to it.
