XCAPI H.323 TechNote

3.5 Incoming Call Handling
With the Incoming Call Handling Treatment dialog, you
can configure unique call treatments for different
incoming calls on any ISDN trunk group.
This chapter is not essential for setting up
the XCAPI-related H.323 trunking, but shortly
described for giving an overview of this example
used numbering and the call handling. Here, the
inc-call-handling-trmt trunk-group 1
is used with a called length, see parameter Called Len,
of 6 digits. This describes the number of digits received
for an incoming call, which consist of the following
three parts.
The local Called Number 450 specifies the leading
digits received for an incoming call, which becomes
deleted again shortly after its detection by the
parameter Del valued with 3.
The Auto Alternate Routing (AAR) Access Code
number 6, as described in the chapter Feature Access
Codes (FAC) starting on page 12, is assigned to the
Feature Access Code (FAC) call type of the Dial Plan
Analysis, described in Dial Plan Analysis starting on
page 13.
The according Automatic Alternate Routing (AAR)
configuration, described on page 14, with the dial string
number 6 and a minimum and maximum digit length
of 3, shows that the calling range 600 to 699 is routed to
the XCAPI-H.323 Trunk.
3.6 Feature Access Codes (FAC)
The Feature Access Code (FAC) configuration dialog
assigns the dialed codes to the system features, which
in turn needs to be defined through the dial plan, as
described in the chapter
Dial Plan Analysis starting on page 13.
Here, the Auto Alternate Routing (AAR) Access Code
number 6 is used for accessing the XCAPI trunk and
the Auto Route Selection (ARS) - Access Code 1 numbered
with value 0 is used for accessing the public network.
