■Local messaging — Messaging services are provided to remote users
by the regional office.
■Global messaging — Messaging services are provided to users locally,
by the either a regional office or a branch office.
For local and global messaging, you need to perform the steps in this
section on a console attached to each IP Messaging server in all regions
(Region 1 and Region 2 in this example).
For Global Voicemail Integration, the Global Voicemail Central Servers
(GVCS) must be installed, and then configured 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 System Administration Guide
for more information and for configuration options.
Once you have installed and configured a GVCS, you can add existing IP
Messaging servers to the Global Voicemail Integration system by running
the vcx-reconfigure command on each server (see Chapter 7).
IP Messaging servers are typically configured in pairs, with one server
acting as the primary and the other acting as the secondary. The primary
IP Messaging server and a secondary IP Messaging server may be located
in the same region or in different regions.
To upgrade the IP Messaging servers:
1Stop the primary IP Messaging server and a secondary IP Messaging
server by entering the following commands, as root, on each server:
cd /opt/3com/VCX/scripts/rc3.d
./S60ums stop
2Obtain a copy of the vcx-ipmsg-7.1.yc.tar software upgrade file and
place it in the /opt/installtemp directory on the primary IP Messaging
server and on the secondary IP Messaging server.
3Upgrade the primary IP Messaging server by following these steps:
aStart the upgrade process by entering the following commands:
