Using Auto-Registration - Cisco ATA 188 Administrator's Manual

Using Auto-Registration

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:

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.
By default, both Cisco ATA FXS ports are enabled for Cisco CallManager registration. If
Note
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.)
