Telephoneusers can use VPIM to send voice mail to a user on any voice mail systemthat is VPIM-compliant.The system transmits VPIM voice mail messages by attaching them toe-mail messages. The system then uses SMTP (Simple Mail TransferProtocol) or ESMTP (Extended Simple Mail Transfer Protocol) to send thee-mail message and its VPIM attachment.VPIM uses an SMTP server that is embedded in the operating system. Toavoid abuse by spammers, always protect an SMTP server with a firewall.Configure the firewall to allow access to UDP port 25 on the system onlyfrom valid VPIM systems that need to deliver VPIM messages to thetelephone system. The NBX SMTP server is started only when the systemhas a valid license for VPIM.VPIM is an optional component that requires a license, which appears inthe NBX NetSet Licenses window as Internet Voice Messaging License.You must enter a license key through the NBX NetSet utility before youcan configure and use VPIM.Use the NBX NetSet utility to configure VPIM settings, check the status ofVPIM queues, and obtain statistics of recent VPIM activity.
