Upgrading a Multi-Site VCX System with Branch Offices

ls -l /opt/3com/VCX
The symbolic link (VCX) should point to the new version of the VCX
software (7.1.xc). If the link does not point to the new version, wait a few
minutes and reenter the command. This could take several minutes and it
is important the link pointer is correct before proceeding.
Example Output:
/opt/3com/VCX -> /opt/3com/VCX.7.1.xc
Some multi-site VCX systems have regional offices and branch offices.
Each branch office is associated with a regional office.
Multi-site VCX systems can be categorized by the method used to
implement messaging.
In a multi-site VCX system configured to use local messaging, the IP
■
Messaging server is co-located with the IP Telephony server at each
branch office. In this case, each branch office provides messaging
services for its users.
In a multi-site VCX system configured to use global messaging, the IP
■
Messaging server is located on the regional office. Each branch office
runs the IP Telephony server only. In this case, the regional office
provides messaging services for users at each branch office.
In version 7.1 multi-site VCX systems, you can configure branch and
■
regional sites to use Global Voicemail Integration. Each location must
be running IP Messaging services, which means that, in a multi-site
system configured to use global messaging, you cannot enable Global
Voicemail Integration on a branch. You can, however, enable Global
Voicemail Integration on the region providing IP Messaging services to
the branch.
This service is provided by a pair of Global Voicemail Central Servers
(GVCS) to enable global voicemail integration on an entire IP
Messaging system.
A GVCS coordinates mailbox creation and mailbox updates on
regional and branch office IP Messaging servers. The version 7.1
upgrade procedure allows you to enable global voicemail integration
on servers running IP Messaging software. However, you must install
IP Messaging software on a GVCS, and then set up the GVCS through
the IP Messaging administrator configuration interface before
enabling global voicemail integration on regional and branch office IP
Messaging servers. Refer to the IP Messaging Module Operations and
