3 Introduction Telephony stack is ready for commercialization It is a proven qualified stack with modem chip vendors in industry Full compliant telecommunication functionalities SIM, SIM phonebook, SIM application toolkit Network registration, Voice/Video call service, Managing SMS/CBS Supplementary services Packet service It already supports well-defined interface with connman. Benefits for commercialization Flexible plug-in architecture Inter-process communication plug-in Modem interface plug-in Keeping maintenance for commercialization readiness. GCF certification Can be well customized for various carrier requirements and manufacturer s proprietary requirements Various carrier requirements can be easily customized with plug-in capsules Manufacturers do not need to have obligation to open their proprietary implementation *GCF : Global Certificate Forum 3 3/
