Configuring ISDN BRI trunk boards
Perform the steps in this section only if you have one or more ISDN BRI trunk boards installed.
Configuring Calling Name Identification
Depending on your ISDN provider, Calling Name Identification is delivered in an Information
Element (IE) either when the incoming call is offered (in the SETUP message) or on a
subsequent FACILITY message.
When you order Calling Name Identification, request the following information from your
provider:
Q Message in which the calling name is delivered
Q IE in which the calling name is delivered
Q Offset within the IE where the calling name field begins
Q Length of the calling name field
You specify this information via the TeleVantage Administrator for each ISDN BRI span. See
“Setting location and Caller ID settings” in Chapter 5 in Administering TeleVantage for details.
Enabling IE-based audio connection
On ISDN BRI spans, audio connection is based on Information Elements (IEs) that accompany
PROGRESS messages.
Q When turned off, TeleVantage connects audio on all ISDN BRI calls only with the IEs
1 and 8 on PROCEEDING, SETUP_ACK, and ALERTING messages.
Q When this feature is turned on (the default), TeleVantage connects audio on all ISDN
BRI calls regardless of PROGRESS IEs.
This feature is controlled via a TeleVantage registry value, HandleProgressInd . Add this
setting for each ISDN BRI board in your system. See “BRI board settings” in Appendix J in
Installing TeleVantage for details.
Configuring TeleVantage for delivery of overlapped DNIS digits
By default, TeleVantage is configured for complete delivery of DNIS digits on the SETUP
message. Some European ISDN providers deliver DNIS digits one at a time after the SETUP
message (overlapped digits.)
You can make changes to the DNIS digit delivery settings OverlappedDNIS and DNISWaitTime
via the TeleVantage Administrator for each ISDN BRI span. See “Optimizing your ISDN
settings” in Chapter 5 in Administering TeleVantage.
