I’ve been having some issues with TLS 1.0 on my Asterisk 18.2 system and I’ve been collaborating with another Asterisk user to try to figure out the issue. The end goal is to get all my ATAs, many of which are out of support, to use TLS/SRTP.
This other person had it working on his Asterisk 16 system but it stopped working for him as well when he upgraded to Asterisk 18. I checked the release notes and I see no mention of TLS 1.0 in the 16, 17, or 18 release notes. Was TLS 1.0 support intentionally removed from the latest version?
I don’t like TLS 1.0 personally, but IMO some security is better than none, and right now my ATAs are failing to negotiate and can’t do anything newer than TLS 1.0, so if it was removed, would there be an issue in forward porting chan_sip.c from v16 to v18?
