chan-dongle-extended on RasPBX?

[MatejKovacic]

Hi, I "accidentaly" found your project, but I think is is just something I have been looking for a long time.

A little background. Almost a year ago I wrote a pretty extensive guide how to install RasPBX. It is published here:
https://github.com/MatejKovacic/RasPBX-install

Now the problem is, that calls are going just fine, but I have a problems receiving SMS messages. Some messages are sent in several e-mail messages, I do not receive MMS messages and I am (still) unable to get SMS messages to my Signal number.

Signal app is a secure messenger, but there is Signal API script, which lets you send Signal messages through REST API. Basically, I can write this (from terminal):

echo "{\"message\": \"On $(date '+%m. %d. %Y at %H:%M:%S') you have received SMS message.\", \"number\": \"+XXXXXXXXXXX\", \"recipients\": [\"+YYYYYYYYYYY\"]}" | /usr/bin/curl --user 'user:password' -X POST -H "Content-Type: application/json" -d @- 'https://signalapi.myserver.net/v2/send'

And I will receive a Signal message.

Of course I tried to put this command to into the /etc/asterisk/extensions_custom.conf, but I do not receive any Signal message.

Anyway, I think it would be really great if there will be detailed guide for setting up your application to RasPBX, but I think I would need a little help.

RasPBX is actually Raspbian GNU/Linux 10 (buster) with kernel: Linux 5.10.103-v7l+. Debian_version says it is 10.12.

How to install chan-dongle-extended to this system?

Also, please note that my working installation is more than 1000 km from me, so I can not afford any mistake...

Hi @MatejKovacic,

Thanks for reaching out,
Absolutely RapPBX should be fully compatible with chan-dongle-extended.

This command should do it:

wget -nc -q -O - garronej.github.io/chan-dongle-extended-pages/install.sh | sudo bash

Unfortunately I have 0 bandwith for helping on redactin any guide but I can help you debug.

Also, please note that my working installation is more than 1000 km from me, so I can not afford any mistake...

I have tons of Rapberry and 3G dongles if you want to SSH to one of them be by guess!

[garronej]

PS: Have you checkout the documentation website? https://garronej.github.io/chan-dongle-extended-pages/

[MatejKovacic]

OK. I have ordered a GSM dongle from Aliexpress, but I am still waiting to get it. But when I do, I will test it extensively. Till then, it would be nice if I can SSH to one of your testing machines. Is it possible that you initially install RasPBX 10.10 (raspbx-10-10-2020.zip file) on a SD card? I would like to make an accurate clone of my installation and then install chan-dongle-extended on a top of it.

[garronej]

Ok I'll do that tonight or tomorrow night.
What rasperry pi model would you like to test with?

I have the 3 and every earlyer model but no 64bit

[MatejKovacic]

I prefer RaspberryPi 4 (because that is my setup too), but I have successfully tested RasPBX with RPi 3 too.

[MatejKovacic]

Also, I have a question regarding current chan-dongle. Because that might also be a problem of your version of it.
I have Huawei E1752 and quite often the GSM Registration Status is not Registered, home networkbut changes to Not registered, but searching or Not registered, not searching.

chan-dongle commands gives me this:

  GSM Registration Status : Not registered, but searching
  RSSI                    : 17, -79 dBm
  Mode                    : No Service
  Submode                 : No service
  Provider Name           : NONE

Or:

  GSM Registration Status : Not registered, not searching
  RSSI                    : 0, <= -113 dBm
  Mode                    : WCDMA
  Submode                 : WCDMA
  Provider Name           : NONE

The funny thing is I tried to send SMS to my number when this happens, and it goes through. I am suspecting there is a problem that GSM dongle is not listening to 2G only, but that it "flips" to some other network (Edge, 3G...), but I am not sure about that. Do you have any experience with this?

[garronej]

Hi @MatejKovacic,
Yes, I have experience with this,
chan-dongle-extended takes mesures to mitigate thoses issues.
I don't remember exactly what it does, I wrote the code a long time ago, but I do remember investigating the issue and I think it's sending some AT command at the initialisation about it...

[MatejKovacic]

Aha, you are probably sending AT commands to work on 2G only. SO I guess my gut feeling was right.

Hi but has anyone managed to install it on the raspbx? Thank you very much

[garronej]

Sorry, I am completely overwhelmed, I don't have time to work on this but I can confirm for sure that it works with Raspbx

[garronej]

I you take an older version, from back when I build this, it will work out of the box. With newer version you might have to do some light tweak to make it work but nothing unsurmontable:

[maisx2021]

gives me this error

[garronej]

The problem is here:

chan-dongle-extended/src/bin/installer.ts

Line 940 in 4428553

const ast_ver = scriptLib.sh_eval(`${ast_cmdline} -V`).match(/^Asterisk\s+([0-9\.]+)/)![1];

In the transpiled JS file it's:

chan-dongle-extended/src/bin/installer.ts

Line 940 in 4428553

const ast_ver = scriptLib.sh_eval(`${ast_cmdline} -V`).match(/^Asterisk\s+([0-9\.]+)/)![1];

What does it tel you when you run asterisk -V ?

[maisx2021]

my version is Asterisk 16.13.0

[maisx2021]

[garronej]

Exctly, what dors it print when u rien Asterisk -V
Sens me a screenshot

[maisx2021]

[garronej]

Ok thanks, strange.
If you want you can email me SSH credentials to your Raspberry.
I can try figuring out what's wrong

[pie-rs]

appreciate I am very late to the party here but @maisx2021 did you get this working ever?
