10 LEAST COST ROUTING
ECOTELs are connected between the customer’s private branch exchange (PBX) and the public telephone network
(PSTN) and/or VoIP. The customer saves connection charges and can effortlessly and automatically connect to the
carrier as needed using the following routing method:
 Carrier selection
Calls are routed transparently for the PBX and its users. ECOTELs can generate charges and route calls using alter-
nate settings in case of network failures.
The following additional services are supported by this feature package:
 Generation of charges
 Time-controlled configuration
 Alternative routing
10.1 CARRIER SELECTION
Carrier selection is currently one of the most commonly used routing methods supported by the ECOTEL. In the
ECOTEL, this routing process also includes calls in the mobile network or through a VoIP network. That means the
system is a full-fledged second generation LCR.
10.1.1 ROUTING ENTRIES
Use the
MapAll command to route calls using Carrier Selection.
a) Use the following syntax for connections routed via the provider:
MapAll<AreaCode>=9<CarrierSelection><AreaCode>
where <AreaCode> is the number or number range to be routed and <CarrierSelection> is the
access number required to reach the provider’s network.
b) For unrouted connections (placed via the public telephone network), use:
MapAll<AreaCode>=9<AreaCode>
c) To block undesired carrier selection prefixes use:
MapAll<CarrierSelection>=&91;(Busy signal)
In the following example, calls to international destinations are terminated through the VoIP interface. The profile
names iG1 and iG2 in the routing entries refer to different VoIP carriers. All other national long distance and local
calls are routed through an alternative carrier (01019). All calls from the PSTN or VoIP to the PBX are put through
transparently.
