About dialing services__________________________________
Your Strata CS Server can place outbound phone calls over several different types
of trunk. A Strata CS dialing service is used to manage calls over a specific type
of trunk. For example, a Phone Number dialing service is used to manage calls
over a group of PSTN trunks, while an Internet Address dialing service is used to
manage calls over a group of Internet trunks. A dialing service creates a
prioritized list of trunks that can be used to place the call. The call is then allocated
to the highest priority available trunk.
Each dialing service has an access code that users must dial when they begin to
place a call. The access code tells Strata CS which dialing service to use. For
example, users might dial
9 plus a phone number to use a Phone Number dialing
service, or 71 plus an IP address to use an Internet Address dialing service.
Dialing service types
Strata CS supports the following types of dialing services:
n Phone Number service. Used to dial standard phone numbers over the
public telephone network. You can specify long distance prefix, area
code, and other information to reflect the telephone company’s dialing
plan. For many installations, a Phone Number service is the only type of
dialing service needed.
See “Adding a Phone Number dialing service” on page 8-10.
n Centrex/PBX Extension service. Used to dial Centrex extensions, PBX
extensions, or other custom numbers over analog and digital trunks that
are connected to external switches such as the phone company’s Centrex
service or an external PBX. You can specify the minimum and maximum
digits your Centrex/PBX service uses.
See “Adding a Centrex/PBX Extension service” on page 8-12.
n Internet Address service. Used to dial Internet addresses over Internet
trunks. With this service, users can pick up a phone and dial an IP address
(for example, a number such as 123*456*78*90) to connect to H.323
devices such as NetMeeting. Users can also place such calls from the
Client using either IP addresses or domain names (for example, a name
such as
voip.mycompany.com
).
See “Adding an Internet Address service” on page 8-14.
n Internet-to-Phone Number service. Gateway service used to dial a
phone number through another Strata CS Server at a remote location. The
call connects to the remote Server using the Internet or a private TCP/IP
network, and then the phone number is dialed from that Server.
