Operafone IP Executive Installation Guide

LAN IP solution

• An Opera Flexicom/4.12em system must be equipped with an Applications card with one IP

channel license per user (maximum 8). Opera 20IP/4IP does not require an Applications card.

• One valid IP address for the Opera system from within the customer’s private LAN address

range.

• LAN port adjacent to the Opera system to facilitate connection to the customer’s LAN.

Security

A Unique IP registration name or extension name and IP registration PIN or password are

required for each remote worker for security reasons.

All connections (e.g. call set-up) and voice streams are encrypted using an advanced encryption

algorithm.

Recommendations

Up to 8 remote workers supported: these may be on one site, subject to bandwidth

availability.

In the case of the 4800, Application Card required for compression and echo cancellation,
