• Easy to use, reliable, high-speed VOIP server.
• Suitable from small business companies to enterprise grade voip carriers.
• It's low cost/high ROI, high call density, powerful routing, reliable SIP,H323 and rtp stack can help you to become the most competitive company in the VOIP market.

Mizu VOIP Server main benefits:

• Ease of use: with the MizuManage client program you can administrate all components in a highly intuitive manner. Most of the settings will be set automatically for you.
