What Mizu WebPhone is
Mizu WebPhone is a SIP-based VoIP client that can be embedded in a webpage or used as a JavaScript SIP library. It handles inbound and outbound voice calls and lists video, chat, SMS, conferencing, recording, hold, and transfer among its call controls. The self-hosted client runs on the buyer’s web server, so users do not download a runtime. Multiple SIP and media engines are selected according to browser, operating system, and server support. Listed security includes SIPS, TLS, DTLS, SRTP, and end-to-end encryption for WebPhone-to-WebPhone calls. MizuTech lists compatibility with Asterisk, FreeSWITCH, FreePBX, Cisco, Twilio, and Vonage, plus Salesforce integration. The interface can be branded, and the JavaScript API supports custom functionality. Basic costs $990, paid once, Advanced $1,990, paid once, and Gold $3,900, paid once, each a perpetual license.
