10 Mobile Least-Cost Routing (MLCR)
The following explains how to actively use the features Callback, Call through, and SIM
Switch.
About MLCR
It is possible to configure number patterns (first couple of digits of a phone
number) which will trigger an automatic least-cost routing. These 'routing
rules' can be deployed to the AMC from the AMCC (please refer to the Aastra
Mobile Client Controller Administrator Manual). However, a different routing
feature can be selected manually by the user even if these routing rules are
present, refer to 8.5.
10.1 (HTTPS) Callback
Use Callback to reduce costs of outbound calls made via the AMC. In a Callback call
the call to both the A- and B-party are setup from the PBX. How to start a Callback is
explained in
8.5
on page 26. If your company makes global use of the MLCR, dialing
certain phone numbers might trigger a Callback automatically! Rules for automatic
routing can be made and deployed to the AMCs using the AMCC.
Note:
The HTTPS Callback request goes through a data connection that might not be
available or fail. In the case of failure, the AMC will automatically fall back to a Call-
through call. The call is still placed through the PBX, however, you do not have the cost
benefits anymore.
