1. How to Quickly Prepare Communication Infrastructure in a New Small Business?
Initial Setup
A network administrator plans to deploy an ISG50 for VoIP services in a new small company. First, it is necessary to prepare extension numbers,
as well as enable voicemail and call forwarding for the current employees in the Sales and Marketing departments. In order to allow road
warriors to register with the ISG50 using their smart phones during business trips, the network administrator needs to define the firewall rules
since the ISG50 works as an all-in-one gateway.
Create Extensions
Goal to achieve: Create two authority groups for Marketing department and Sales department, and add 5 extensions in Marketing department.
Condition:
Authority Group: Marketing and Sales
Extensions for Marketing: 3100-3104 Pin Code for Marketing: 3100-3104; Password for Marketing: 53100-53104
