Works perfectly if you're using a DIY SIP VoIP system. Our phones were powered by Asterisk with Flowroute handling all of the actual SIP traffic. No issues whatsoever.

Open Source
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.

Open Source
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.
