Just a clarification, so you have added the first ATA 186 to CCM with the given MAC address (example 001A2B3C4A5B).

When you add in the second ATA 186 (same device just second port) you are changing the first digit to 01.

So, are you making the new MAC address 011A2B3C4A5B? or 1A2B3C4A5B01?

Because you should be dropping off the first two characters of the MAC address and adding the 01 to the end. So, 1A2B3C4A5B01 would be the correct configuration.

How do you turn off the second port on an ATA? I would like it not to register with Call Manager and thus use up DLUs for unused ports or cause transient connection errors.

Hi Steve,

Here is the process;

Note: By default, both Cisco ATA FXS ports are enabled for Cisco CallManager registration. If you do not want to add the Phone 2 FXS port to Cisco CallManager, you must change the Cisco ATA EPID1orSID1 parameter value to 0 to disable the Phone 2 port. (To disable the Phone 1 port, you must change the EPID0orSID0 parameter value to 0.)

Hope this helps!
