Telephony & IP Integration System (TIIS) is an IP-based SCP which provides mobile value added services such as Call Keeper, Perfect Call, Multi Call forwarding, Location trace & alarm service, Lettering, Anti spam call/SMS service, and Call gift service.

To provide the value added services, TIIS inter-works with Home Location Register (HLR), Short Message Service Center (SMSC), Automatic Response System (ARS), and Number Portability DataBase (NPDB). TIIS also enables users to directly control the services through the web/WAP.
