[Héctor Jiménez Méndez]

Hello, Alexander!
We will check again after updating to 1.18.

I will share the results once we try it.

Thank you!

Hey Héctor,

Hi, Alex, thanks for your quick answer.
Nice to know you worked at Elecnor/Deimos Space 😊
This is definitely a bug to fix. That transition to "terminated" shouldn't happen when the callee picks up the call. Can you get MM debug logs while reproducing the issue? Also, is this using AT or QMI?
Two logs are attached: one with transition from ringing-out to active and another with the wrong state transition (ringing-out -> terminated).
At first sight I couldn’t find any significative trace to explain this behavior, I hope you can get some related info in them.

I think this "CONNECT" URC is getting in the middle of the +CLCC? polling and it's breaking the logic:

ModemManager[4908]: <debug> [1679560149.943734] [modem0/ttyUSB2/at] --> 'AT+CLCC<CR>'
ModemManager[4908]: <debug> [1679560150.110892] [modem0/ttyUSB2/at] <-- '<CR><LF>CONNECT <CR><LF>'
ModemManager[4908]: <debug> [1679560150.111267] [modem0] reported 0 ongoing calls

Your device is QMI capable and we do see certain Voice events reported in the log via QMI. Full QMI based voice support was introduced in MM 1.18, I definitely suggest you switch to that so that AT-based management is completely skipped.
