VCX Maintenance Tasks 21
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
System Administration Guide for more information and for configuration
options.
With VCX software version 7.0 and higher, you can set up IP Messaging
in a client/server configuration. An IP Messaging server can support up to
20 IP Messaging clients. One client can be dedicated to non-voice
applications such as Web provisioning, e-mail synchronization, and
logging. The remaining clients can be dedicated to voice functions. This
type of setup diverts the stream of voice traffic and improves the IP
Messaging server performance. Clients should be located on the subnet
with both management servers or have a minimum of 200 Mbps IP
backbone on a dual subnet network configuration. See the IP Messaging
Module Operations and System Administration Guide for details.
VCX Maintenance Tas ks
This section describes the maintenance tasks you may need to periodically
perform to, for example, backup a database, add an Accounting service
group to the Call Records service, or upgrade your VCX system software.
This section assumes that VCX software has been successfully installed,
your network is functioning normally, and that you understand your VCX
system configuration (single-site or multi-site).
VCX system communication is based on the Session Initiation Protocol
(SIP). SIP is used to set up, maintain, and terminate connections (calls)
between end points. These end points are SIP-enabled devices such as
telephones, call processors, and gateways. Basically, VCX configuration
consists of identifying and configuring the end points in your VCX
network, and setting up the rules that govern communication between
the end points.
In general, VCX maintenance includes the tasks shown in Tabl e 4. In a
multi-site configuration, some of these tasks must be performed at each
site (regions and branches).
