Use Cases and Deployment Scope
One of our clients wanted SIP to PSTN conversion, but with open source, so after a lot of deliberation, we went with Kamailio SIP Server; we used it for easy conversion of SIP to PSTN. It acted as a firewall where we used to register the SIP signals, and the Kamailio SIP Server will also act as a proxy server to redirect calls to the proper PSTN gateway based on the configurations. It was also a great load balancer and a security firewall for our client's PSTN gateways.
Pros and Cons
  • Proxy server.
  • Security Firewall.
  • SIP to PSTN gateway.
Likelihood to Recommend
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.

Return on Investment
  • As its open source ROI is excellent.
Alternatives Considered
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.
