Installing Networked Messaging (VPNM)
Overview
Voicemail Pro Networked Messaging (VPNM) allows users to forward voicemail to mailboxes on remote
voicemail systems This is done by adding a VPNM component to the Voicemail Pro installation.
The messages are transferred between systems using an SMTP/MIME mail format to encode both the
voice part of the message and additional message details.
Here is a diagram to illustrate VPNM between two IP Office systems.
Here is a diagram of a sample VPNM configuration between an IP Office and Avaya Interchange.
Depending on how your IP Network is set up, the configuration will differ slightly.
Up to 2000 mailboxes are supported per VPNM server and there is no constraint on the number of
VPNM servers. However, to distinguish between dial plans you might need to allocate a dial pre-fix to
each server. A maximum of 99 pre-fixes is available.
This section summarizes the steps required for installing VPNM between two IP Office systems and
between an IP Office system and an Intuity Audix system through Avaya Interchange.
The instructions provided here should be read in conjunction with the other Avaya guides, for example
"Avaya Interchange Release 5.4, Adding a VPIM System to Your Network". This is because the setup for
Interchange VPIM is the same as for VPNM.
