What happened to package siproxd?

Hello, ever since about 3 days ago, my home-office phones stopped being able to connect. When I looked into it, I realized siproxd was crashing. I removed siproxd, in order to purge config files, however, when I went to reinstall, the package is missing from the repos. I kind of need that back up and working.

FWIW, the issue is occurring on my NetGear R8000, running 19.07.5. All software plugins are from official repos.
