Best Open source SIP Server.
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
- Proxy server.
- Security Firewall.
- SIP to PSTN gateway.
Cons
- Interportability
- SIP conversions.
Return on Investment
- As its open source ROI is excellent.
