When you complete and submit the Change Station Extension screen, all administration that was associated with the previous extension is now associated with the new extensions. This administration includes any references used in a vector, in coverage, and elsewhere in the system. Once you change an extension, the software removes all references to the previous extension.
If you change an extension that is also administered on an adjunct, you must also change the extension on the adjunct. Examples of adjuncts include voice mail and an Adjunct-Switch Application Interface (ASAI) link.
Exceptions
The change extension-stationn command does not change the administration that is associated with call forwarding digits and abbreviated dialing buttons on the current extension.
To change a forwarded extension that is administered as a button, do not use the change extension-stationn command. The extension for the call forwarded button is stored as digits rather than as a UID. Avaya recommends that you use the list usage command before you change any extensions.
The change extension-stationn command does not update the ISDN BRI SPID field for BRI telephones. To update this field, you must make manual changes on both the switch and the telephone.
Audits
If you try to change an extension that is administered on the same switch as an emergency location extension on the Station screen or on the IP Address Mapping screen, the system displays the following warning message:
Extension exists as Emergency Location. Continue?
Click yes to process the change. Click no to stop the process.
The change extension-stationn command is be denied under the following conditions:
If the extension being changed is active on a call
If the administrator is accessing the extension
If you attempt to change an extension that is administered on the same system as a media complex extension on the Station screen, the extension cannot be changed to a 6-digit or 7-digit number. The media complex extension field on the Station screen does not support 6-digit or 7-digit numbers.
For example, extension 50002 is an IP (H.323) telephone extension. Extension 50002 is administered on extension 51234 as the media complex. You cannot use the change extension-stationn command to change extension 50002 to 7050002 because the software does not support a 7-digit media complex number. You can, however, use the command to change 50002 to 52222, because 52222 is a 5-digit extension.
