Last Sunday (4/13/25) I reloaded one of my test asterisk servers (never mind why, sad story). After everything was installed (Debian 12, DAHDI, wanpipe and asterisk 22.3.0) my T1/PRI were in “Red Alarm” state (as in they were down). All the software installed without any errors. Same version of DAHDI and wanpipe. And only minor changes in my asterisk .conf files (nothing that would affect the PRIs). The only difference I could find is the version of Debian 12. It went from 6.1.0-32 to 6.1.0-33.
I’m using a Sangoma A102 Dual Port T1 Card.
Reported this the Sangoma Support. And then said to switch back to 6.1.0-32.
I have no idea of how to switch Debian 12 back to a prior version and Google was no help.
Well,I have everything figured out. ESC didn’t work. On this HP PC it took me to a BIOS Setup Menu. But when Debian 12 boots up it displays a menu. The second choice gives a list of available version. The second one was version 32. So I chose it and 32 booted up. . So then I did an apt remove linux-image-6.1.0-33-amd64 and now everything is just wonderful!
Hi Everyone. With Help from Sangoma Support I now have everything back Online. It was Configuration Errors on my part! I’m back on Debian 12 6.1.0-33-amd64 and everything is good.
