Redirecting Altigen Ip Phones When A Server Is Down - Altigen ACM 6.5 Administration Manual

Managing Domain Users
If extension 1001 is relocated from site A to site B, and the administrator creates a
•
local extension 1001 in site A, the extension 1001 will be removed from the REL.
Later, if the administrator removes the local extension 1001 and relocates global
extension 1001 back to site A, this extension cannot be restored to its original
settings.
When an extension is relocated to site B for the first time, the administrator or the
•
user should configure the Call Restriction, Speed Dial list, and so on, for one time in
site B. These configurations will be stored on site B. Later, if the extension is
relocated to site B again, no additional configuration is needed, as the previous
configuration will be restored.
If multiple systems in the VoIP domain have a PRI interface, it's possible that DID
•
numbers could be duplicated. For example, say the DID number for extension 1001
is configured as 250. In this case, the DID number 5102520250 and 4087899250
will ring extension 1001. To ensure that this doesn't happen, you can do one of two
things: (1) Make sure the DID numbers are not duplicated; (2) Ask the CO to send
more digits (to decrease the likelihood of identical DID numbers).
Relocating a Global Extension Using #27 on Analog Phone vs IP Phone
Analog phone: The phone must be off hook. The user presses #27 and follows the
•
voice prompts. User must press # after inputting the password.
IP phone: The IP phone must be on hook. The user presses #27, and then inputs the
•
global extension number and password. The global extension is then relocated to
this IP phone.
If system B does not have a prior record of this extension, it will create a new
extension with known information and the following settings:
Enable IP Extension and Dynamic IP Address settings will be selected
•
automatically (in MaxAdmin, Extension Configuration window).
The newly created extension will use the default voice mail, mail forwarding,
•
notification, call handling, restriction, and monitor list settings (MaxAdmin,
Extension Configuration window).
Note: The administrator needs to make the proper changes for this user when
the global extension is relocated by the user.
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 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
