Timeout making voice call, Huawei e171

[hobodrifterdavid]

I tried running the test script dial_callback_demo.py. Ubuntu 16.04, running on Python 2.7, Huawei e171 USB 3G modem (unlocked and voice enabled). I get this message:

DEBUG: write: AT+CSQ
DEBUG: response: ['+CSQ: 10,99', 'OK']
Dialing number: 0951161251
DEBUG: write: ATD0951161251;
DEBUG: response: ['OK']
Traceback (most recent call last):
File "dial_callback_demo.py", line 71, in
main()
File "dial_callback_demo.py", line 64, in main
call = modem.dial(NUMBER, timeout=10, callStatusUpdateCallbackFunc=callStatusCallback)
File "/usr/local/lib/python2.7/dist-packages/gsmmodem/modem.py", line 728, in dial
raise TimeoutException()
gsmmodem.exceptions.TimeoutException

I plan to look into it myself, but, any hints?

Many Thanks, David

I have a similar problem with the Huawei modem E3531. I tried incoming_callTrial.py and it got stuck at the ¨Waiting for incoming calls.... ¨ message. I called the modem with my phone and I get a line busy message on my phone.
I then tried the dial_demo.py code and the following is what I got. Any ideas of what I can do to get me out of this bind?

By the way, the SMS_handler_demo.py worked. I was able to send an SMS to my Raspberry Pi 3 and I got a reply.
