Call hangs up at mailbox

[UltraBlackLinux]

Hey there, I just noticed some weird behavior with my modem: Whenever my calls reach someone's mailbox, my modem just hangs up the call a few seconds later.

I found the following in the logs: modemmanager.log:

Any idea why I'm getting disconnected? Firmware version is 0.7.1 Thanks!

Can you post the full log from openqti? and eg25-manager log too? The modem port is being disconnected, but I don't see and can't imagine any reason for that to happen just because a call ended...

Oh no I completely forgot about this issue. Here:

The modem also ends the call when trying to call a callcenter.

Edit: I did notice afterwards that the number I tried to call was invalid, so I'm not so sure about that callcenter thing anymore. I can only say, that the wrong number warning also hangs up the call.
