Introduction
This document describes how to disable FXS port 2 on 18x ATA
Core Issue
Port 2 of 18x ATA is constantly trying to register to CUCM 7.x and wants to disable it.
Resolution
To disable the second analog Foreign Exchange Station (FXS) port on the ATA
Use value 0 to disable the port(s) you are not using:
- EPID1 or SID1 for Line 2 or Port 2
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)
SIDx specifies whether to enable the Phone 1 and/or Phone 2 ports on the Cisco ATA to register with Cisco CallManager. (EPIDx is not for SCCP.) SIDx can be one of these values:
- 0 - Disables the port. The port does not attempt to register with Cisco CallManager.
- . or - Uses the default Skinny ID, which is the Cisco ATA MAC address (MAC) for the Phone 1 port and MAC[1-5]+01 for the Phone 2 port. The port attempts to register with 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.
