E173 modem receives SMS only during initialization

[sergei-mironov]

Related to E173 Huawei modem. Dongle seems to communicate with it correctly. I could send SMS from Asterisk CLI. Unfortunately, receiving SMS works only during the initialization of dongle: either on Asterisk restart or after dongle restart now dongle0. I can’t see any reaction from the software when I send SMS if asterisk is already running.

Are there any 'monitoring' modes in gsm modems, that I should enter into to receive SMSs?

Configuration (please ignore unusual format, they are built-in into NixOS expression):

• Asterisk version: 17
• dongle.conf
• extensions.conf

Some status commands:

*CLI> dongle show devices

Talking to myself: A workaround for this issue is

dongle cmd dongle0 AT^PORTSEL=1

One probably need to add it to the chan-driver somewhere.

I have some E173 with the same firmware as you, they receive SMS without any issue on asterisk 1.8, 13 and 15 (at least with my fork https://github.com/miopa/asterisk-chan-dongle)

Talking to myself: A workaround for this issue is

dongle cmd dongle0 AT^PORTSEL=1

I tried this on two E173 (ast 1.8), both modems got stuck on 'dialing' soon
