Chapter 25: Enterprise VoIP Network Management
328 MAXCS ACC 6.7.1 Administration Manual
• When this Global extension user returns to his home office, all settings are
stored in the REL database. The administrator does not need to change these
settings when the user presses #27 to relocate the extension the next time.
Relocating More Than One Global Extension
When more than one global extension is being relocated at the same time, and voice
mail is also being relocated, the voice mail of the extension that was relocated first will
be copied over completely to the relocation site, before copying begins for the voice mail
of the second extension, and so on.
The extension, itself, is relocated immediately.
Redirecting AltiGen IP Phones When a Server Is Down
Relocating a global extension, described in the preceeding section, is intended to serve
employees who are physically relocating to another office for a time. Administrators can
also configure global AltiGen IP phones to register to another server in the VoIP domain
when their primary server goes down for some reason. All configured phones switch over
at the same time. When their primary server returns to service, the administrator can
switch the phones back to their primary server by clicking the Switch Back to Home
Server button in the Servers > Information tab. For more complete information, see
“Setting an Alternate Server for AltiGen IP Phones” on page 319.
Note: When you redirect AltiGen IP phones, voice mail is not moved. Otherwise, the
extension configuration changes of the redirect feature are the same as they are
with normal relocation.
Note: If Native VM Integration with Microsoft Exchange 2007 is also configured, users
can access their voice messages from both the primary and alternate servers, if
both have the same dial plan configured in the Microsoft Exchange server.
Note: Redirection does not work when an extension user is using IPTalk.
Before configuring individual IP phones to redirect from their primary server to an alter-
nate server, an alternate server must be assigned in Servers > Information tab > Al-
tiGen IP Phone Redirect panel. The Redirect option is not available until an alternate
server is assigned. Only AltiGen IP phones that are global and have no conflict with the
extensions of other sites can be configured to redirect.
To configure an AltiGen IP phone to redirect,
1. In Enterprise Manager click Users button > Resolve tab.
2. Select a global IP phone whose server has an alternate server assigned.
Note: The AltiGen IP extension may need to be pre-configured on the alternate server
to match its configuration on the home server, so that it works as expected. (For
example, the alternate server may have a different call restriction policy. The ex-
tension on the alternate server may belong to a different workgroup. The greet-
ings may be different even if the extension number is the same.)
3. Check the Enable Switchover to Alternate Server check box.
Note: If an extension configured with the redirection feature is manually relocated (by
the system administrator in Enterprise Manager or by the user pressing #27), the
redirection feature will be removed on the new site. If the extension is manually
relocated back to its original site, the feature is recovered.
