17.3. Last Calling Service for UMTSBOX

17.3. Last Calling Service for UMTSBOX
	Chapter 17. UMTS BOX

The Last Calling Service is useful to route a call received by a SIM inserted in UMTS BOX, toward the last number which called the calling number.

	Warning
	Last Calling number Service requires a separate licence.

Suppose to have this situation:

CTIP 101 (for example number 200) makes a call to a cell phone (number 320123456);
The call is routed through the UMTS BOX using port CTIP:501 (which corresponds to a SIM whose number is 320654321);
The LCS saves calling and called numbers in the LCS table;
A call is received by UMTS BOX: the called number is 320654321, the calling number is 320123456;
The call is automatically routed toward CTIP 101 (number 200).

Suppose we have a UMTSBOX with port CTIP:501 with the following configuration:

	To activate the changes made on the LCSG, execute the initialization command init ctisys. Remember to save the configuration (save conf).

For the CTIP:501 is necessary to configure the LCS-GROUP parameter, where "1" is the ID:1 of LCSG.

	Important
	For routes towards SIP user is necessary to set the `LCS` parameter to `YES`, to activate the Last Calling Service. Another important parameter of CTIR routing is the LCST: Last Calling number Service records Timeout. The value `Sys` means the default value and will be the one setup by the CTISYS resource.

	Warning
	Changes made on the CTI routing table aren't immediately active. To activate them, execute the initialization command init ctir.

Type the following command to show the LCST entries.

	Note
	The LCST table entries expire after 6 hours (`TOUT` is equal with 6), because the LCST: Last Calling number Service records Timeout is equal to 6.

The phone 320123456 has received a call from 320654321. If the phone 320123456 makes a call to 320654321 the call is routed to number 200 (CTIP:101). The following is the log of call.
