Question

FreeSWITCH

I use certificates for nginx - 2 files:
ssl_certificate /etc/nginx/cert/nginx.crt;
ssl_certificate_key /etc/nginx/cert/ssl.key;
how to install them in freeswitch to support wss?

Answer 1

in agent.pem are important put the contents of nginx.crt and ssl.key in PKI
into cafile.pem CA CA (in my opinion you can do without it)
