Configuring Registration Accounts

The Accounts table lets you configure up to 625 Accounts. An Account defines registration
information for registering and authenticating (digest) IP Groups (e.g., IP PBX) with a
"serving" IP Group (e.g., ITSP).
The device initiates registration with a "serving" IP Group on behalf of the "served" IP
Group. Therefore, Accounts are typically required when the "served" IP Group is unable to
register or authenticate itself for whatever reason. Registration information includes
username, password, host name (AOR), and contact user name (AOR). The device
includes this information in the REGISTER message sent to the serving IP Group. Up to 10
Accounts can be configured per "served" IP Group. A IP Group can register to more than
one IP Group (e.g., multiple ITSPs). This is done by configuring multiple entries in the
Accounts table for the same served IP Group, but with different serving IP Groups,
username/password, host name, and contact user values.
Authentication is typically required for INVITE messages sent to the "serving" IP Group. If
the device receives a SIP 401 (Unauthorized) in response to a sent INVITE, the device
checks for a matching "serving" and "served" entry in the Accounts table. If a matching row
exists, the device authenticates the INVITE by providing the corresponding MD5
authentication username and password to the "serving" IP Group.
Note:

If no match is found in the Accounts table for incoming or outgoing calls, the
username and password is taken from:
