4-4 INSTALLING TELEVANTAGE
Ordering hunt groups
Trunks used with TeleVantage must be configured by the phone company in a terminated hunt
group so that calls roll over to the next trunk if the first one is busy.
In this arrangement, incoming calls try the lowest numbered phone line first. If that line is busy,
they try the next higher phone line and continue trying lines until a free line is found. If you will
be using the same trunks for both inbound and outbound calls, you must configure dialing
services in the Administrator so that on outbound calls, TeleVantage starts searching for a free
line from the highest numbered trunk. This configuration helps to limit glare conflicts on lines.
Ordering inbound- and outbound-only trunks
Inbound-only trunks and outbound-only trunks do not affect TeleVantage performance, but they
may be of benefit in your organization. If you order them, you must configure them in the
Administrator. See Administering TeleVantage for details.
Ordering emergency dialing service
Consult your local phone company to determine the emergency dialing services that are
available in your area. For information about using Enhanced 911 service, which is designed to
help the local emergency dispatching center identify the precise location of a caller making an
emergency call, see “Enhanced 911 service requirements” on page 3-23.
Ordering call waiting
It is strongly recommended that you do not order call waiting on analog trunk lines. TeleVantage
provides its own call waiting tone to users on incoming calls. If telephone company call waiting
tones arrive as well, they can confuse users.
Ordering ISDN Two B-Channel Transfer service
With ISDN PRI trunks using the NI2 protocol, Two B-Channel Transfer allow you to transfer
incoming calls to external numbers without consuming TeleVantage trunks while the external
callers are connected. For more information, see Administering TeleVantage, Chapter 5, “Using
Two B-Channel Transfer.”
Note:
When ordering this service from the phone company, TeleVantage does not require the
“Notify on transfer” option.
