Hello All, I  have installed kamailio with TLS module together with siremis on server and all seems works fine  except that sometimes appear in syslog file the following errors: /usr/sbin/kamailio[3266]: ERROR: <core> [tcp_read.c:289]: tcp_read_data(): error reading: Connection timed out (110) /usr/sbin/kamailio[3266]: ERROR: <core> [tcp_read.c:1281]: tcp_read_req(): ERROR: tcp_read_req: error reading /usr/sbin/kamailio[3268]: ERROR: <core> [tcp_read.c:289]: tcp_read_data(): error reading: Connection reset by peer (104) Some part of syslog please you find enclosed. I don't know where I should search for the cause of these errors and how to debug and remove them. I don't know if these errors are caused by incorrect kamailio configuration or are caused on client's side. Thank you for your opinions and  help in advance Regards, Petr
