2.2 Internal Call Routing
Internal call routing refers to calls between extensions on the X6004. People simply dial the
extension they want to call. The X6004 checks to see if the number dialed is an existing
extension and forwards the call to that extension. The X6004 by default allows people with
extensions from one authority group to call extensions in another authority group. You can,
however, block calls between authority groups if your organization requires such a setting.
The configuration requirement for setting up internal call routing are:
1 Create an authority group.
2 Create extensions in the authority group.
2.3 Outbound Call Routing
Outbound call routing refers to calls originating from an extension on the X6004, going via an
outbound line group to a telephone outside your organization. Outbound call routing requires
that an authority group is linked to an outbound line group. The link between the two is an
LCR (Least Cost Routing). LCRs contain the dialing rules for outbound line groups. Authority
groups need to be associated to LCRs to gain access to the outbound line groups.
In the most basic setup example an organization has one authority group (with all of the
company’s extensions), one outbound line group and an LCR which grants the authority group
access to outbound lines. Everyone in the organization has the same rights to use outbound
lines.

In a more advanced example, you can create two authority groups, still have one outbound line
group and two different LCRs. You can now control the types of outbound calls that can be
made by each authority group.
In the figure below, the SALES authority group has a local call LCR and a long distance LCR
associated to it. This allows its group members to make both local and long distance calls via
the outbound line group. R&D authority group only has the local LCR associated to it so its
group members can only make local calls via the outbound line group.
