Managing Telephones
Changing from dual-connect to single-connect IP telephones
When you have a dual extension telephone and you upgrade to a single extension telephone,
you can remove the connection that is no longer used for that telephone.
To remove the H.323 connection that is no longer needed, first record the media complex
extension number:
1. Type change station nnnn, where nnnn is the extension number of the original
dual-connect telephone that you are replacing with a single-connect telephone.
The Station screen appears.
2. Move to the Media Complex Extension field.
3. Write down the number in the Media Complex field, then delete the number from the field.
4. Press Enter to save your changes.
Now remove the extension you recorded. Before you remove an H.323 extension from your
system, check the status, remove it from any group or usage lists, and then delete it from the
system's memory.
For example, if you wrote down extension 1234 before you removed it from the Media Complex
field on the Station screen, then remove extension 1234 using these steps:
1. Type status station 1234. Press Enter.
The General Status screen appears.
2. Make sure that the extension:
is idle (not making or receiving calls)
●
has no messages waiting
●
has no active buttons (such as Send All Calls or Call Forwarding)
●
3. Type list groups-of-extension 1234. Press Enter.
The Extension Group Membership screen shows whether the extension is a member of
any groups on the system.
4. Press Cancel.
5. If the extension belongs to a group, access the group screen and delete the extension from
that group.
For example, if extension 1234 belongs to pickup group 2, type change pickup group 2
and delete the extension from the list.
6. Type list usage extension 1234. Press Enter.
The Usage screen shows where the extension is used in the system.
7. Press Cancel.
