Description

We noticed that configuration option tcp_accept_iplimit was included in newer kamailio versions (most notably 5.7.4), and it was a breaking change for us. Added sample configuration value in /etc/kamailio.cfg file - already tested in our production deployment.

Looks good to me, its also just a comment in the end. Lets wait a bit more for feedback and then merge it.

Fine for me to add it to the default config file etc/kamailio.cfg, but the commit message should be updated to reflect that, not the prefix tcp/docs: is not suggesting at all it is about etc/kamailio.cfg.

Thanks, it was merged manually due to a wrong commit message.
