Hello,

first, look at doc/tcp_tunning.txt in the source code tree to get some hints on scaling the capacity for tcp (under-layer for tls).

Then, tls handshaking failure can happen from various reasons, you can run kamailio with debug=3 in config and see more details about what is happening when the failure happens. You can send the relevant messages here to be able to assist further.

Cheers, Daniel

Hi All,

We are trying to make 10000 tls connection with Kamailio server for SIP signaling.When I try beyond 6500 TLS connection then TLS handshake is failing.We are running the kamailio by using below command

• kamailio -f kamailio.cfg -N 40 -m 1024 -M 16

NOTE: In kamailio.cfg, we have mentioned tls_max_connections=60000

Could you please guide me, how can I improve the tls connections with kamailio ?

Thanks Priyaranjan
