28.14 Configuring ISDN Supplementary Services
The ISDN Supp Services Table page allows you to configure supplementary services for
Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) phones connected
to the device. This feature enables the device to route IP-to-Tel calls (including voice and
fax) to specific BRI ports (channels).
This table allows you to define BRI phone extension numbers per BRI port pertaining to a
specific BRI module. Therefore, this offers support for point-to-multipoint configuration of
several phone numbers per BRI channel. Up to eight phone numbers can be defined per
BRI trunk. For each BRI endpoint, the following optional configurations can also be defined:
User ID and password - for registering the BRI endpoint to a third-party softswitch for
authentication and/or billing. For viewing BRI registration status, see 'Viewing
Endpoint Registration Status' on page
689.
Caller ID name - for displaying the BRI endpoint’s caller ID to a dialed destination, if
enabled (i.e., “Presentation” is not restricted)
Caller ID presentation or restriction
Enable/disable sending caller ID to BRI endpoints
Notes:
• To use this table for routing of IP-to-Tel calls to specific BRI channels,
the Channel Select Mode in the Hunt Group Settings must be set to
'Select Trunk by ISDN Supplementary Services Table' (see 'Configuring
Hunt Group Settings' on page 297).
• The ISDN Supp Services table can also be configure using the table ini
file parameter, ISDNSuppServ or CLI command, configure voip > gw
digitalgw isdn-supp-serv.
• To allow the end-user to hear a dial tone when picking up the BRI phone,
it is recommended to set the Progress Indicator in the Setup Ack bit
(0x10000=65536). Therefore, the recommended value is 0x10000 + 0
x1000 = 65536 + 4096 = 69632 (i.e., set the ISDNInCallsBehavior
parameter to 69632).
To configure BRI supplementary services:
1. Open the ISDN Supp Services Table page (Configuration tab > VoIP menu > GW
and IP to IP > Digital Gateway > ISDN Supp Services).
