2025-11-23 The TLS certificate on sip.sdf.org is expired, which
prevents Linphone (my softphone client) from connecting. UDP is
working fine, but I'm not keen on unencrypted SIP dialogs in 2025.
Created a post in the REQUESTS bboard to see if someone can take
care of that. We'll see how that works.

I also created this gopher hole.
