• B - Connecting several ISG50s together to manage a larger telephone network.

Scalable Design 

Automatic Call Distribution (ACD) allows you to distribute incoming calls to specific groups of 
phones connected to your telephone network. Distributed calls can then be sent to individual people 
based on assigned skill sets. This is known as Skill-Based Routing (SBR). When the ISG50 receives 
an incoming call, it categorizes the call by “skill”. Next, it assigns the call to the one of the agents 
associated with that skill. Skills are defined by the ISG50 administrator and constitute a set of rules 
that work in tandem with the auto-attendant to assign incoming calls to groups of agents.

The Click-To-Talk (CTT) feature allows you to create an HTML link that you can embed on a Web 
page; a person visiting that web page can click it to connect to one of the ISG50’s extensions.

This feature gives users the freedom to access their telephone extensions anywhere in the world, 
regardless of the type of telecommunications device they are using: cell phone, VoIP, or landline. 
The “mobile” aspect that the end user can always be on the move and still receive calls sent to their 
telephone extension.

To ensure the ISG50 provides reliable, secure Internet access, set up one or more of the following:

• Multiple WAN ports and configure load balancing between these ports.
• A 3G (cellular) connection.
