Toll Restriction Service (TRS) Restrictions
DBS networking provides the ability to make outside calls via a distant
networked DBS. To restrict or enable network outside calling by an extension
on the local DBS, the extension is assigned a TRS type for each Network
Trunk Group used.
Enter the TRS Restrictions for Extensions Calls to Outgoing Network Trunk
Groups in Table 2-43 through Table 2-46.
