73.18. How to configure Last Calling Service

Assuming to have an UMTSBOX (ports 501,502), let's configure the Last Calling Service so that a call received by the SIM inserted in the port # 501 of the UMTSBOX is routed to the last number which called the calling number.

Enter into the Abilis control-program or open the configuration file with the Console configurator and type the following commands.

a lcsg id:1 cb-permit-cd:*Configure the LCS group.
s ctip:501 lcs-group:1Configure the LCS group.
init ctisysInitialize the parameters of CTI ports and the LCS groups.

CTI routing configuration:

a ctir pr:0 poi:pbx out:501 cdi:?* sp:64000 lcs:yes lcst:6 descr:From_PBX_to_UMTSBOXAdd a CTI rule to route a call incoming from PBX to UMTSBOX.
a ctir pr:1 poi:501 out:pbx cdi:* sp:64000 descr:From_UMTSBOX_to_PBXAdd a CTI rule to route a call from UMTSBOX to PBX.
init ctirInitialize the CTIR resource.
save confSave the configuration.

Last Calling number Service requires a separate licence.


Check the LCS table to verify the association between calling and called number.
