4S Proxy/Registrar
The Proxy/Registrar is the main signalling unit of any VoIP infrastructure based on SIP (Session Initiation Protocol).
The snom 4S Proxy is a fully-fledged SIP proxy/registrar supporting any SIP-compliant device.
It manages user and registration data and handles signaling of calls based on SIP.
The snom 4S Proxy can be used stand-alone or as part of an existing VoIP system.
Depending on your requirements it can be scaled anywhere from SOHO to ITSP.
There are three levels of web interface (system, domain and user-level),
which allows you to administer the system at three completely independent levels.
Each user can configure his individual settings and use value-added services such as click-to-dial from the user-level web interface.
Multiple domains can be administered independently on one machine.
This makes it easy for providers or resellers of VoIP services to service different customers at a minimum of infrastructure and cost.
