CodeB SIP Bridge and VPN

As the world moves its telephone traffic to VOIP it creates new challenges. Typically VOIP uses the Session Initiation Protocol (SIP) to negotiate the session and the Real-time Transport Protocol (RTP) for the Media Streams. This all creates a huge amount of dynamically created TCP and UDP connections.

While this works flawless in the intranet it becomes more challenging if firewalls have to be crossed. For example for remote workers, etc.

To solve those issues Aloaha developed a SIP VPN / SIP Bridge which basically bundles/multiplexes all TCP, UDP and RTP connections on the client side into one single HTTP connection (Websocket).

The server component de-multiplexes all those connections and connects them with the SIP Server.

Features

  • Client multiplexes all SIP UDP, TCP and RTP connections into one single HTTP(s) connection
  • Server de-multiplexes the HTTP(s) tunnel and connects UDP, TCP and RTP to SIP Server
  • Client and Server offer plugin interfaces to trigger actions based on calls
  • Automatically re-writes SIP headers
  • SIP sanitizer included
  • Stir/Shaken supported
  • Access to CodeB Identity System
  • Client does not require any installation
  • 100% managed code
