Redirecting AltiGen IP Phones When a Server Is Down
Relocating a global extension, described in the preceding section, is intended to serve employees who are
physically relocating to another office for a time. Administrators can also configure global 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 330.
Notes:
• 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.
• If Native VM Integration with Microsoft Exchange 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.
• Redirection does not work when an extension user is using IPTalk.
Before configuring individual IP phones to redirect from their primary server to an alternate server, an alternate
server must be assigned in Servers > Information tab > AltiGen 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 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 con-
figuration on the home server, so that it works as expected. (For example, the alternate server may
have a different call restriction policy. The extension on the alternate server may belong to a dif-
ferent workgroup. The greetings 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 configuration is
dropped on the new site. If the extension is manually relocated back to its original site, the feature is
recovered.
Changes to AltiGen IP Phone When Redirect Is Configured
After the redirection feature is configured, the IP phone will receive the configuration of the primary and
alternate server address, and store them in its local flash memory. Once it has been configured for redirection,
the IP phone’s “AW Server” address will be that of the primary server. The user can view the address on the
IP phone (Menu > System > AW Server) but cannot configure it. When redirect is enabled, "Primary Server"
and "Alternate Server" are added to the phone’s System menu. They are read-only.
