Title:

Carrier VoIP Security

Steven L. Spak
Distinguished Member of Technical Staff

Abstract:

The coming international network migration to IMS (IP Multimedia Subsystem) infrastructure will depend heavily upon SIP (Session Initiation Protocol). Carrier experience with SIP in pre-IMS VoIP deployments have highlighted the complexity their suppliers encounter in implementing robust SIP platforms. The security mechanisms specified within the SIP standard must be supplemented by special network engineering and security management in order to maximize network and resource availability.
