Can you update to v1.1.0 to see if that works with your modem? It should fall back to class 1 since it doesn't support class 2.

[paloke]

The -f parameter works correctly, it picks up and answers like a FAX.
But, in normal mode, it doesn't pick up and hangs up. I think the time between picking up and hanging up is too fast. I have done the sequence manually, in a terminal, and the HAYES commands are correct.

ATZ
OK

ATH0
OK

AT+VCID=1
OK

AT+FCLASS=0
OK

DATE = 1112
TIME = 2144
NMBR = 987654321
NAME = P

RING
ATH1
OK

ATH0
OK

And was the call picked up correctly? Looks like yes but I just want to confirm.

[paloke]

Yes, the call was answered correctly.

[AT0myks]

I added a 1 second delay before the hang up. Please install from source (pip install git+https://github.com/AT0myks/pycallblock.git) to see if that fixes the issue.

[paloke]

Sorry, I haven't been able to test it, the VM where I have the modem installed doesn't have git.
