33.1.1 What You Can Do in this Chapter

Use the Group Management screens to view and manage the associations for the authority and

outbound line groups configured on the ISG50. See

The following terms and concepts may help you as you read through the chapter.

Managing Authority Groups

You control extensions within an authority group by associating (linking) authority groups with:

• Other Authority Groups - When you create an authority group it is by default linked to all other

authority groups created on the ISG50 and all the other authority groups are also linked to it.

This means that any extension created on the ISG50 can call any other extension created on the

ISG50 regardless if they are part of the same authority group. You can, however, stop extensions

within one authority group from calling extensions in another authority group. An example is

shown below. You have an organization with three authority groups (AG1-AG3). You can remove

the link from one authority group (for example AG3) to another authority group (for example

AG2) to stop extensions in AG3 from calling AG2 (AG2 can still call AG3).

• LCRs - An LCR is an outbound dialing rule. When you create links from an authority group to an

LCR, you allow the extensions in that authority group to make outbound calls via the outbound

line groups configured in the LCR. The following figure shows AG1, which is an authority group

for the sales department, associated with LCR1 (this could be an LCR allowing calls through your

local telephone service provider - PSTN and calls via a link to your branch office - TrustedPeer)
