Use one of the following methods to administer subscribers on the Message Networking system (in order of preference):

• Use FTP to add subscribers.
• Use self-registration to add subscribers' voiced names.
• Send a message from the new subscriber.
• Register through the Administration page.
• Initiate Bulk Add by Range from the Message Networking system.

• View the Remote Machines List to verify that the new remote machine is listed.
• View the Remote Machine Dial Plan List to verify that the new remote machine is listed.

Administer the Message Networking system as a VPIM network node on the VPIM system. You'll need the following information:

• The fully qualified domain name and IP address of the Message Networking system. The VPIM system uses this information to send messages to the Message Networking system. You can find this information on the General Parameters page on the Message Networking system.
• The Message Networking network address length. You can find this number on the General Parameters page on the Message Networking system.
• The Message Networking network address ranges for other messaging systems in the network. Depending on the specific VPIM system, the address ranges that are required might extend just to the area code or the local area code + exchange prefix. In other cases, you might need all digits of the address ranges.
  

Note: The VPIM system must pass to Message Networking only those addressing digits used in the Message Networking network. When using telephones, subscribers on the VPIM system might have to dial additional digits to address messages to remote subscribers on the Interchange network. These digits might be required for the following reasons:

• The VPIM system can identify the addressee as a remote subscriber.
• The VPIM system can identify the remote system where the remote subscriber resides (in this case, the Message Networking system).

Do not administer the VPIM system to pass any other digits to the Message Networking system. Instead, administer the VPIM system so that it strips off these additional addressing digits when it passes the message to the Message Networking system. Only addresses within the ranges specified for Message Networking remote machines (specified in the Dial Plan Mapping) are to be sent to the Message Networking system.
