C5 is the core building block of our platform and the technology base for all Sipwise products. It provides SIP, XMPP and WebRTC, signaling and media interfaces towards customers and peerings, it relays and bridges voice and video streams between different technologies and supports secure communication via encrypted channels. A powerful REST API, an administrative/customer web interface and billing export interfaces allow simple operation of the system.
C4 bridges VoIP and PSTN via SS7, providing voice origination and termination as well as IN services like Local Number Portability and Fixed Mobile Convergence. In addition, it supports different ISDN interfaces for various use cases. Powered by Dialogic(tm), we have achieved full integration into our C5 provisioning systems through our joint technology partnership
