How do I get port 2 to register to the Cisco CallManager?
A. Refer to How to Configure Cisco CallManager to Recognize ATA 186 Using SCCP. Complete these steps in order to add the second port on the Cisco ATA 186 to Cisco CallManager: • Drop the first 2 nibbles of the MAC address and shift the MAC address to the left. • Add 01 to the right end of the MAC address. For example, 00070EA26032 is port 1 and 070EA2603201 is port 2. • Use this new MAC address and register this as a device to the Cisco CallManager.
