You can further benefit from my ten years of experience with Internet Standardization, mainly IETF (Internet Engineering Task Force), ranging from various aspects of TCP/IP to designing and developing real-time communications systems. You'll get an expert in SIP (Session Initiation Protocol) with all its surrounding aspects including emergency call routing, ENUM (E.164 Number Mapping) and E2MD (E.164 to MetaData).

My prior responsibilities have led to expertise that addresses your core needs. These responsibilities include 3GPP (3rd Generation Partnership Project) IMS (IP Multimedia Subsystem) and IETF SIP Standardization at Nokia, leading the national level trial of ENUM in Switzerland at SWITCH, as well as Innovation Management in product development at Swisscom.
