Thanks for your work on ca_path. It is so that currently ca_path can only be given as tls module config parameter and not in tls config file. I tried like this:
modparam("tls", "config", "/etc/sip-proxy/tls.cfg")
tls.cfg:
[server:default] verify_certificate = yes require_certificate = no server_name = lohi.tutpro.com tls_method = TLSv1.1+ private_key = /etc/sip-proxy/certs/key.pem certificate = /etc/sip-proxy/certs/cert.pem ca_path = /etc/sip-proxy/certs/ca_list
and got error at start:
Mar 23 11:47:18 lohi /usr/bin/sip-proxy[25175]: ERROR: <core> [core/cfg_parser.c:731]: sr_cfg_parse(): tls.cfg:7:1: Unsupported option 'ca_path'
