Mobile Least Cost Routing (optional)
The Mobile Least Cost Routing function (Mobile LCR) minimises mobile roaming
expenses by routing the call through the least expensive path. The logic is based on
an LCR table managed by the system administrator via the Aastra provisioning portal
and via the Aastra Mobile Client over-the-air provisioning system. Aastra Mobile Cli-
ent uses the LCR to determine which call method is the most cost efficient for each
call. The options are:
• Automatic HTTPS callback
• Call through
• Direct cellular
The function is transparent to the user of Aastra Mobile Client, and works from any
mobile network.
Automatic HTTPS callback function (MX-ONE™ only)
When you are abroad, it is usually less expensive to receive a call than it is making one.
The Aastra Mobile Client solution automatically selects the least expensive method in
each case.
When you make a call, the call is established in the background. The Aastra Mobile Cli-
ent sends the signals via the mobile phone data channel to the MX-ONE™ system.
The HTTPS callback setup time might take longer than a call when you are at home
and not making a roaming call. During the setup of the call a text is displayed, e.g.
Waiting for Callback .
If the Mobile LCR call setup fails, Aastra Mobile Client makes a direct mobile call and
the Mobile LCR is deactivated during the call. The reason for a failed call connection is
usually a lack of GPRS or 3G data connection.
Notes:
• The first time you use the HTTPS callback function you might get a message to
approve a HTTPS certificate. Answer yes to the question and the call will be estab-
lished. Next time you call the mobile phone you should have the HTTPS certificate
and not get the question again. If you do, please contact your Aastra Mobile Client
administrator.
• The Aastra Mobile Client will frequently download the LCR table from the LCR
AMC portal (configured by the AMC administrator). If LCR table download fails, an
error message will appear in the AMC GUI.
