Hi All. We are trying to get SIP TLS working, but have run into a snag. We followed this documentation - https://wiki.asterisk.org/wiki/display/AST/Secure+Calling+Tutorial - but, when it comes to PJSIP, we are bit lost on the authentication process. For example, in that documentation, the peer has assigned a username and password. However, in our case, we are simply doing IP-based authentication. I've tried Googling and all that, but I am not coming across an answer (I am probably not searching correctly). Anyways, how would I go about using an IP address to authenticate the peer for TLS, not a username/password? Thank you, Alex -------------- next part -------------- An HTML attachment was scrubbed...
