SIPERB (Session Initiation Protocol Endpoint Relay Bridge) is a SIP Proxy that sits between your traditional VoIP/SIP PBX (like Asterisk or FreeSWITCH) and our WebRTC Browser Phone client. It provides all the tools you need to enable WebRTC calling on your traditional PBX. Your Asterisk PBX may not be WebRTC ready, or it may be, but you lack the Browser Phone required to make use of WebRTC, or you may just want more of the features that SIPERB offers. Either way, SIPERB can provide this for you.
