ATA 186 on Call Manager 5

[nickmac74]

Hi can any one give advice on how to configure the 2nd port on an ATA 186

Port 1 works fine - but wanting to set up port 2 - I read that you have to take off the first two digits of the mac and pot 01 at the end?

e.g. 00-ff-ff-ff-ff-ff and replace with ff-ff-ff-ff-ff-01

Is this the case? if so when you set it up will it have a different IP address to the one for port 1?

Many thanks in advance

Hi Nick,

You are most correct :) The ATA will only use one IP Address.

Use this procedure to add the second port on the Cisco ATA 186 to Cisco CallManager.

Drop the first two nibbles of the MAC address and shift the MAC address to the left, then add 01 to the right end of the MAC address. For example 00070EA26032 is port 1 and 070EA2603201 is port 2.
