    Kamailio SIP Server is very well suited if you want to secure your main servers; it can perfectly act as a proxy server and a gateway to your main server. It also does load balancing and call transfers easily based on the configurations done.

    • I think at performance level it is still to be improved as many time we face hang issues but i think that can be imrpoved soon by the company
    • Having different configuration UIs on Web/App/Cloud, where it makes difficult to remmeber the exact places where to make changes. THere should be some syncing in configuration options
    • service support to be improved.

    As Kamailio SIP Server is an open source, the major impact is on cost; it's free to use compared to any other Softswitch or server in the market. You can also customize it to your need and use the features that you need, which is one of the major plus points for the Kamailio SIP Server. And one server is enough to handle thousands of calls simultaneously.

    • Hard to quantify.
    • We seem to get more clear voice mails
    • The ability to get an email when you miss a call and can access your voice mail from anywhere helps with managing time
