Logging modem dialout attempts

[biketool]

My Pinephone Pro running Trixie is able to do everything normally re:modem except successfully dial out, that includes taking incoming phone calls.
I am not sure where the logging is kept to look for errors etc when accessing the modem in order to troubleshoot the issue, possibly also need to look at logs inside the modem module OS.
Has anyone else had this issue in the current trixie since middle of last week?  
The SIM dials out successfully in a 4g dumb Nokia.

I am looking around and I would like to find the documentation on how the phosh calls app triggers a call vs perhaps dialing on the CLI, lockfiles etc so I can see where the call is failing.

Unfortunately some of the mmcli example websites have bitrotted away so we dont have the required documents to do a CLI test...
(edit)
ma mmcli helped a little

Code:

mobian@mobian:~$ sudo mmcli -m 0 --voice-create-call=number=1231231234(fake number for this post)
Successfully created new call: /org/freedesktop/ModemManager1/Call/1

but it throws no CLI error just fails with a doo doo doo tone and is done.

there are some powerful mmcli tools to do things like clear stuck SMS/MMS and other things but finding the documentation is a matter of scraping hundreds of blog and forum posts some of which are referred to as master documentation but are not online anymore.

(edit)
I forced 2g and now I can out dial over the CLI and calls app and it works in/out...(I had thought I had tried this before)
3g - voice in/out works, data/SMS works
4g - voice(call out fails in app and cli, no cli error) but can receive voice calls, data/SMS works (same SIM works on 4g with newer Nokia dumb phone...IDK)

Ideas?
