Please retry on the latest community supported version. Certified versions are only intended for people with paid support contracts and only in the configurations for which support is provided. I would assume that compiling on an unapproved OS would void the certification, as would compiling with any change to the build settings (e.g. I don’t think that version is certified for use with chan_sip, so enabling chan_sip would void the certification).
This afternoon I installed Debian 13 on one of my test servers. Asterisk-23.0.0-rc2 and Used phreaknet to install DAHDI 3.4.0. I think that worked, but I did see a couple of Red messages that flashed by on the screen. The DAHDI utilities seem to work.
The only problem seems to be Sangoma wanpipe. It would not install due to Kernel level problems. Debian 12 is 6.1.0 and 13 is 6.12.48. So my T1 circuits are down.
So if you have Sangoma hardware cards stay on Debian 12 until Sangoma updates wanpipe.
