I am facing a strange issue with some of my endpoints. I am using TLS for both media and transports. Asterisk 18.4 with PJSIP.
I am getting regular ssl error messages as follows;
[2021-06-02 17:31:13] WARNING: pjproject: <?>: SSL 6 [SSL_ERROR_ZERO_RETURN] (Read) ret: 0 len: 65535
Moreover extensions seem indefinitely register and get deleted.
A trace of the debug output, transport and endpoint confing are being attached.
