The Mizu SIP/H.323 signaling and media stack is a result of our 10+ years of work and experience in VoIP.

The SIP/H.323 protocol stack provides all necessary SIP, SDP and RTP functionality, such as encoding, sending, parsing and receiving SIP messages, managing SIP transactions and ensuring reliability.

The server side libraries were written with throughput and stability in mind, while on the client side the compatibility is our first priority.

The SIP stack is available on the following platforms
    -C++: both server and client libraries used mostly on Windows OS
    -Java: cross-platform client libraries (java applets and applications, android)

The server side sip stack uses the MS-SQL database backend (necessary for advanced features such as VoIP Billing)
