    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.
