Latest modem firmware breaks voice calls

[bero]

Hi,
after installing the modem firmware from
https://forum.pine64.org/showthread.php?tid=11815

Trying to make a voice call results in an "Unknown error". ModemManager points ad "org.freedesktop.ModemManager1.Error.MobileEquipment.Unknown".

$ mmcli -m 0 --voice-create-call=number=MYNUMBERHERE 
Successfully created new call: /org/freedesktop/ModemManager1/Call/1
$ sudo qdbus --system org.freedesktop.ModemManager1 /org/freedesktop/ModemManager1/Call/1 org.freedesktop.ModemManager1.Call.Start
Error: org.freedesktop.ModemManager1.Error.MobileEquipment.Unknown
Unknown error

Any idea what went wrong here? Is there any other firmware build to try?

Nop : you will find all the commands to make a voice call on my site : https://www.alsatux.com/Pinephone (at bottom).
And you have a syntax error : your forgot the " around the number=MUNUMBERHERE on the first command.
But if someone made the full process using DBus only on CLI, it will be very cool to share here...

$ gdbus call --system --dest org.freedesktop.ModemManager1 --object-path /org/freedesktop/ModemManager1/Call/CALLID --method org.freedesktop.ModemManager1.Call.Start

Command tested !

Hi, I suspect that, as expected, the update reset your modem's configuration settings.
Please carefully re-read this thread: https://forum.pine64.org/showthread.php?tid=11815

You may wish to try booting a more modern OS image with a 5.9 megi kernel, as it should set the relevant settings for you.

Hi,
thanks, but that's definitely not the problem -- I'm on the 5.10 megi kernel, git checkout from today.

The problem seems to be that the modem just doesn't register with the carrier anymore after updating the firmware. AT+CREG? and AT+CEREG? show "0,5". AT+COPS=? shows (correctly) the list of available networks.
AT+COPS=1,2,"networkidentifierhere",7 says OK but doesn't connect, AT+CREG? remains at 0,5.
I suspect something broke/disabled roaming - I'm trying to connect to a German cell tower with a Swiss SIM card. This worked before playing with the firmware though.
