Before the device burned down, on the Raspberry Pi, a service was running through a 3G modem(Huawei 3131), for recording incoming calls and had a service for sending SMS messages.
Now that I’m not able to get a RaspberryPi, FreePBX is installed on the PC.
I need to somehow activate a 3G USB flash drive.
Of course, I ran into a number of problems there. And I would like to ask you to help me solve the problem so that the system will initially work.
I have installed FreePBX 16.0.21.9 on my PC.
Current system version: 12.7.8-2208-2.sng7
USB modem: Huawei E3131 with SIM card.
When run the command ls -l /dev/ttiUSB* I get the following:
[root@freepbk ~]# ls -l /dev/ttiUSB*
crv-rv---- 1 root dialout 188, 0 Nov 14 12:25 /dev/ttiUSB0
crv-rv---- 1 root dialout 188, 1 Nov 14 12:25 /dev/ttiUSB1
crv-rv---- 1 root dialout 188, 2 Nov 14 12:25 /dev/ttiUSB2
When enter the asterisk -r command:
freepbk*CLI> dongle show devices
Then I get the message:
“There is no such command ‘dongle discovery’ (type ‘core show help dongle discovery’ for other possible commands)”
I don’t have options for the dongle, nor to change and configure the dongle.
The chan_dongle module is not part of Asterisk or part of FreePBX. It is external, so if you haven’t done the work to get it installed then it won’t be present.
My impression is that chan_dongle isn’t being maintained, so you may find there is a ceiling on the version of Asterisk under which it will run.
I’d certainly expect that you would need to compile it from the source code.
The advice for those wanting mobile air interface access in a commercial environment is to use SIP to air interface gateway, connected over Ethernet. Raspberry Pi /chan_dongle, is, basically a hobbyist’s configuration.
I don’t understand why you are not able to obtain a replacement Pi.
I was also thinking that I should probably find an older version of Asterisk that would be compatible with the chan_dongle currently found on popular sources.
The delivery time Raspberry Pi, as well as the current price are not profitable for me for this small venture.
