4-2 INSTALLING TELEVANTAGE
Introduction _____________________________________________
Trunks are the phone lines that you order from the telephone company. This chapter describes
requirements for the trunks and services that you can use with TeleVantage.
Note:
Placing VoIP calls over the Internet or your private TCP/IP network does not require
additional telephone company trunks. See “VoIP requirements” on page 4-10 for more
information.
Connecting and configuring trunks
Connecting trunk lines to the Dialogic trunk boards in your TeleVantage Server PC is covered
in Chapter 6 in Installing Dialogic Telephony Components. Once connected, you must configure
your trunks via the TeleVantage Administrator. See Chapter 5 in Administering TeleVantage for
details.
Using trunks with TeleVantage ______________________________
There are two ways to use trunks with TeleVantage:
Q Install one or more Dialogic telephony boards that provide trunk resources of the type
that you want to use (analog, T1, E1, or ISDN BRI) on the TeleVantage Server. See
Chapter 4 in Installing Dialogic Telephony Components for details.
Important:
For the most up-to-date board specifications, refer to the Excel file
SupportedTelephonyBoards.xls, included on Dialogic Drivers CD.
Q Use a SIP gateway device with FXO/T1/E1/BRI ports to provide VoIP connectivity
options to trunks. See “Using gateway PSTN/FXO ports with TeleVantage” on page 6-2
or “Using IP gateway T1/E1/BRI ports with TeleVantage” on page 6-3 for details.
Note:
If you use a gateway, the trunks must meet the requirements of the gateway
itself, which may be different than Dialogic trunk board requirements described in this
chapter. See the documentation that came with your gateway for details.
