Hello,

as tcp is a trasport easier to exploit for attacks, there is a limit of how many connections can be active. You can increase it as you need, see the core cookbook:

Cheers, Daniel

Hi All I am using Kamailio 4.0.4 (x86_64/linux). I wanted to do simultaneous registrations of large number of endpoints.

Many times I see only 2048 endpoints registered and for other endpoints Kamailio did not respond for REGISTER message.

I am tcp as transport.

Now my questions are

1. What are the different configurations available to increase

Kamailio performance 2. If I put Kamailio in a Linux 64 Bit, 2GHz, 8GB RAM machine, how much simultaneous and total registrations can be achieved.

I have tuned system file FDs, tcp related configurations like ephemeral port range, and other required configurations.

I hope there should be some configurations in Kamailio to achieve higher throughput , can somebody help me out.

Thanks Austin
