Cisco Systems ATA 186, ATA 188 manual Using Auto-Registration

Chapter 4 Adding the Cisco ATA to the Cisco CallManager

Using Auto-Registration

•If you want to add a second Cisco ATA FXS port to Cisco CallManager, you need to fabricate a MAC address for the Phone 2 port by dropping 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.

Example

If the MAC address of the Cisco ATA is 00070EA26032, then the fabricated MAC address for the Phone 2 port would be 070EA2603201.

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.)

Using Auto-Registration

Use auto-registration if you want Cisco CallManager to assign directory numbers automatically to new Cisco ATAs as they connect to the IP telephony network. Once a Cisco ATA has auto-registered, you can move the Cisco ATA to a new location and assign it to a different device pool without affecting its directory number.

To perform auto registration, see the applicable release version of the Cisco CallManager Administration Guide at the following location:
