Primary Rate Interface (PRI), Answering Calls
Description
The system provides flexible routing of incoming PRI calls to help meet the exact site requirements. This
allows PRI calls to ring and be answered at any combination of system extensions. Many of the options
available to incoming analog trunk calls are also available to incoming PRI calls.
Delayed Ringing
Extensions in a Ring Group can have delayed ringing for PRI trunks - just like other types of trunks. If the
PRI trunk is not answered at its original destination, it rings the DIL No Answer Ring Group. This could, for
example, help a secretary that covers calls for their boss. If the boss doesn’t answer the call, it rings the sec-
retary’s phone after a programmable time.
Calling Name Delivery
If provided by the telco, and depending on the version of your system software, the system can support call-
ing name delivery in the Facility Information Element. With this information available, display telephone
users can see the name of the calling party.
Caller ID
With Caller ID enabled, the system will provide information for ISDN calls that do not contain the Caller ID
information. If the Caller ID information is restricted, the telephone display will show “PRIVATE”. If the
system is not able to provide Caller ID information because the telco information is not available, then the
display will show “OUT OF AREA”.
SMDR Includes Dialed Number
The SMDR report can optionally print the trunk’s name (entered in system programming) or the number the
incoming caller dialed (i.e., the dialed ISDN digits). This gives you the option of analyzing the SMDR report
based on the number your callers dial. (This option also applies to a DID trunk as well.)
Calling Party Number Notification
The system can provide calling party number notification for outgoing ISDN calls. When a call is made on
an ISDN line by an extension, the system will send the identification for the extension placing the call, if it’s
programmed. If there is no Extension Calling Number assigned, the system will send the calling number for
the ISDN trunk. If both the extension and trunk information is programmed, the extension information will
be sent as it takes priority.
When the option for calling party subaddress is on, the extension number will be sent as the subaddress infor-
mation. Both the calling party number and calling party subaddress are sent in a SETUP message as the calling
party information element and a calling party subaddress information element. Allow the system to send the
subaddress by setting the following programs: 10-03-05=1, 15-01-04=1, 20-08-13=1, 21-13-01=enter number
to be sent.
Calling Line Identification Presentation
CLIP display available with software 1.02+.
A Class of Service option has been added which can be used to allow the Calling Party Number IE in the
Setup Message.
Calling Party Allowed or Prevented for Extension
Calling Party allowed for extension with software 1.04+.
The system allows the Calling Party Number for outgoing ISDN calls based on the extension’s set up in Pro-
gram 15-01-04 : Basic Extension Data Setup - ISDN Caller ID. If this option is to be enabled, then it must
also be enabled for the BRI or PRI PCB in 10-03-05 : PCB Setup - CLIP Information.
