Phoning through different Telecommunication Carrier
7 Phoning through different Telecommunication Carriers
Everyone is looking for ways to spend less on telephone calls. Due to the recent
deregulation of telecommunications in many countries, several further telecom-
munication carriers are offering their services. Frequently, connections outside
the local area, i.e. long-distance calls, can be more economical when “rerouted”
through an alternative carrier.
You can determine which connections you would like to route over low-cost
carriers: long-distance calls, international calls, and connections into the cellular
net. Incidentally you can also assign the outside line access and thus all external
calls to a certain carrier.
Price comparisons will have to be made though. Take into consideration differ-
ent rate tables, zones, periods, etc., special rebates, amount of communication,
access conditions and so on.
7.1 Routing Methods
No settings
are necessary on the TELES.iPBX 8TR Box for the
Call by Call
or
preselection
methods used by different telephone companies or carriers (see
Glossary).
The TELES.iPBX 8TR Box offers two further conveniences for cost-effective
telephoning:
•
Automatic dialing through preferred network carrier,
simplifying the Call
by Call method (section 7.1.1, page 54).
•
Direct Line Access with Subaddressing
– the direct automatic dialing of a
network carrier’s dial-in node that, for example, determines the most eco-
nomical connection rate (section 7.1.2, page 54).
