Abstract
The subject matter described herein provides systems and techniques for adding an identity (ID) header to IP packets associated with a VoIP call. This ID header may be used to authenticate the source provider/originator of a VoIP call, may be used to traceback to the source provider/originator of the VoIP call, and may be used to create a relationship between the source provider/originator and the destination provider/destination of the VoIP call. Such steps may be performed by a public proxy/platform. The ID header may include a certificate and/or a public encryption key, from a public certificate authority (CA) infrastructure, which assists in authenticating the source provider/originator of the VoIP call. The public proxy/platform may directly route authenticated VoIP calls through a VoIP network towards its destination, bypassing a public switched telephone network (PSTN).
