If anyone is interested, I run my own minimalist fork of Molly named Polly.

I just released a stopgap with the fixes: - RingRTC 2.73.0-1, which includes the call-teardown fix (the hangup/hot-mic issue) - Signal's blacklist of the eight compromised eMudhra TLS intermediates

https://github.com/lone-cloud/polly/releases/tag/v8.19.2-6

It's still based on Signal 8.19.2. The build is arm64-only and Android 14+.

Plug: I also maintain my own UnifiedPush distributor app that optionally pairs with a notification gateway: https://git.lonecloud.dev/lone-cloud/prism-android My motivation for Prism was to get Proton Mail email notifications delivered via UP, which requires a self-hosted Prism server.
