How to configure the second line on the Cisco ATA 186

By Brad Reese on Fri, 04/04/08 - 2:27am.

The Cisco Analog Telephone Adaptor (ATA) 186 is a handset-to-Ethernet adaptor that interfaces regular analog phones with IP-based telephony networks.

The Cisco ATA 186 has two voice ports that were designed to support legacy analog touch-tone telephones.

In order to configure the second line or port, you need to drop the two left-most digits from the Cisco ATA MAC address and add the digits 01 to the right-most portion of the MAC address in order to fabricate a MAC address for the Phone 2 port.

This is an example:

If the MAC address of the Cisco ATA is 00070EA26032

Then the fabricated MAC address for the Phone 2 port is 070EA2603201

For more detailed information, refer to Step 7 in the:

Manual Configuration of Cisco CallManager 3.0, 3.1, 3.2, or 3.3 to Recognize the ATA 186

Additionally, refer to:
