Hi, I’m trying to connect to the asterisk pbx via wss, from demo page (

I used the guide from , to setup the tls. I could make a secure sip call ( SRTP) using the PhonerLite sip client. ( This confirms my sip – tls settings and tls certficates. (
I’d added the tls client certficate file to the configuration of the the sip client)

In the WSS option, I assume browsers negotiates for the the tls certficate and keys.

Below are my debug code and the brief logs, http.conf :
Here, ssl_err is my addition to debug further, in main/tcptls.c

else if (ret == 0)

} else {
