Hi All

I am having a sip client, I am using GNU tls for transport layer security.

I am using Kamailio (TLS enabled) to test all the functionalities.

I did registration over TLS. It was fine.

I tried to make call.

I was able to send INVITE.

Kamaiio trying to connect to called party (which is again my sip endpoint).

That time certificate verification failed.

Error log

8(14180) ERROR: tls [tls_server.c:1193]: tls_read_f(): TLS write:error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed
8(14180) ERROR: <core> [tcp_read.c:1326]: tcp_read_req(): ERROR: tcp_read_req: error reading
8(14180) DEBUG: <core> [tcp_read.c:1481]: release_tcpconn(): releasing con 0x7f962f6b6db8, state -2, fd=5, id=3

How do I debug and fix this issue.

Can somebody help me out.

Thanks

Austin
