Auto Registration ATA 190 – Dual registration

I don’t mess around too much with ATA devices, and I think never configured one that supports 2 DNs/FXS ports. I was surprised that when configuring Auto-Registration and connecting the ATA 2 devices came up with 2 devices, I was unsure so I looked around to get more information on this one.

I used Auto Registration to save me some time.

Here is the text from Cisco’s website on the ATA’s

Adding the ATA 190 with Auto-Registration

By enabling autoregistration before you begin installing the ATA 190, you can:

Automatically add devices without first gathering MAC addresses from the ATA 190.
Automatically add an ATA 190 to the Cisco Unified Communications Manager database when you physically connect the phone to your IP telephony network. During autoregistration, Cisco Unified Communications Manager assigns the next available sequential directory number to the phone.
If you want to change settings, quickly enter devices into the Cisco Unified Communications Manager database and modify any settings, such as the directory numbers, from Cisco Unified Communications Manager.
Move autoregistered devices to new locations and assign them to different device pools without affecting their directory numbers.

Note Support exists for autoregistration for several devices in the Unified CM at the same time.
Autoregistration is disabled by default. Sometimes, you may not want to use autoregistration. For example, if you want to assign a specific directory number to the phone or if you plan to use secure connection with Cisco Unified Communications Manager as described in the Cisco Unified Communications Manager Security Guide. For information about enabling autoregistration, see the Enabling Auto-Registration in the Cisco Unified Communications Manager Administration Guide.
Note For mixed mode, autoregistration is automatically disabled and cannot be changed. For nonsecure mode, autoregistration is disabled by default but can be enabled manually.

Adding the ATA 190 with Cisco Unified Communications Manager Administration

You can add the ATA 190 individually to the Cisco Unified Communications Manager database using Cisco Unified Communications Manager Administration. To do so, first obtain the MAC address for each device.

For information about determining a MAC address, see Determining the MAC Address of an ATA 190.

After you have collected MAC addresses, in Cisco Unified Communications Manager Administration, choose Device > Phone and click Add New to begin.
Note ATA 190 has two FXS ports, and each port has its MAC address. The first ATA 190 port uses the MAC address and the second ATA 190 port uses the shifted MAC address (example, AABBCCDDEEFF to BBCCDDEEFF01). You can add two devices from the Unified CM administration page.
For complete instructions and conceptual information about Cisco Unified Communications Manager, see the Cisco Unified Communications Manager Administration Guide and the Cisco Unified Communications Manager System Guide.
