Configuring inbound & outbound GSM (chan_dongle) connections in FreePBX

In the previous video, I showed you how to install RasPBX on Raspberry Pi and turn it into a fully functional Freepbx-based GSM Gateway. Today we continue the series and we will add a custom dongle trunk, add inbound & outbound routes, and of course ..... test our setup.
Hardware: Rapberry Pi 4, Huawei E169, Huawei E173
Software: Raspberry Pi OS lite, Asterisk 16, chan_dongle

Great tutorial. Exactly what i was looking for. :D .. Thank you

@HOTKEY404 is there a video for freepbx using usb_modeswitch to setup gsm dongle ?

[@tuansahith7843]

hi. can i install freepbx to the desktop pc & conncet dongle as a gsm gateway? if so, do u have any video for setup & configuration? Thanks.

[@balanu835]

can you suggest which USB dongle will support this option

[@robinthompson9604]

Can the channel mobile work with USB cable as opposed to Bluetooth. Just concerned about voice quality loss over Bluetooth and also when more then one phone connected.

[@dann-emilzamora4112]

Hi! Do you have a working Rapbx with a SMS System?

[@JanD-sn8mf]

Hey! I'm new to FreePBX. I've set up Raspbx on a Raspberry Pi 4 and would like to make calls using a 4G SIM router (TP Link - TL-MR6500v/ VoLTE, VoIP, VoiceMail). The router works fine on the RJ11 port with a standard phone. I previously attempted to use the chan_dongle module, but it appears that the 4G SIM doesn't work with it. I don't believe the mobile carrier provides any SIP settings for 4G SIMs. Is it possible to connect the VoIP router with Raspbx over Ethernet?

[@zabawymatyldy6501]

czy jest mozliwosc przeprowadzenia analogicznej konfiguracji na CentOS?

[@Subgunman]

Will this work on a standard sized computer with FreePBX running? Is there a specific dongle I should ask for from my provider to use with this setup or will a data only USB device work?

[@HOTKEY404]

chan_dongle can be compiled with any Asterisk-based software. List of compatible dongles can be found here: wiki.e1550.mobi/doku.php?id=requirements

Sprawdź czy bo reboot malinki dongle będą nadal przypisane tak samo? U mnie co reboot zamieniały się porty miejscami co powodowało zamianę numerów przez co wychodzące i SMS odwrotnie funkcjonowały. Pomogła konfiguracja po imei zamiast po portach USB

[@HOTKEY404]

To prawda, że ustawienia po IMEI mogę rozwiązać problem - o ile system poprawnie wykryje modem (spotkanie się z modemami, gdzie po IMEI nie działało). U siebie go nie zauważyłem, dopóki nie wypinałem modemów. Przy założeniu, że się korzysta z jednego modemu, to nie będzie problemem 😜 Ale słuszna sugestia!

[@lionelnkurunziza2733]

thanks a lot! Running on Asterisk 16.26.1, chan dongle driver comes by default or it has to be installed after!

[@HOTKEY404]

Hi. In many systems you can just use install-dongle. Others might require usb_modeswitch packages

before any dongle to use you must check voice supported

[@HOTKEY404]

Right 👍 We provided the list in one of the comments

[@richmadrid9563]

is there an Android/iPhone version of the Softphone app, so you could make/receive calls or send/receive SMS from your home country on your mobile phone, when you're abroad? Coz as you know you need to do bank transactions, you'll need your home country mobile number to receive SMS or calls for 2-factor authentication.

[@HOTKEY404]

You can send/reveice SMS and they will appear in Asterisk. Then you can create eg. AGI or ODBC functions to forward them to your phone/email/sql/etc....

[@mrraulpeedeejay6166]

I would like to know if there is a utility that allows both to send and read the sms received using a web page. Thank You

[@HOTKEY404]

There is an incoming video on how to create such web page yourself. It will consist of simple PHP script and AMI connection. So stay tuned 😉 Unless you need this immediately, then contacts us via email.

What does mean mode and submode of modem? is it important?

[@michaeln8171]

is it bad, if i have mode 0 (no service), submode 0 (no service)

[@handsomepappi]

I have few questions as I'm way to understanding the whole setup and no complete info is available online for a GSM setup. My questions are: 1- Can I register one of the extensions of this pbx on a SIP application on mobile and use it remotely to make calls via GSM dongke? By remotely I mean out of my local network. 2- Similarly, if I receive call on gsm dongke can I route those calls to a SIP extension registered on a SIP application on a mobile? Purpose of this is to make and receive calls over a mobile SIP application when I'm travelling. Thank you very much in advance.

[@HOTKEY404]

Of course you can do all of that. You just need to create and extensions and 1) do a port forwarding to PBX - remember about security issues eg. do NOT open UDP 5060 to the world or 2) use a VPN to connect your mobile phone to your PBX These are the most common scenarios

[@dededobre]

@@HOTKEY404 Hi, nice tutorial about using cell dongle with Raspberry Pi for incoming and outgoing calls. I have a similar question as Michael X. I wonder if this GSM gateway would work with no extra connection to the Internet other than this dongle. Would I be able to connect (register) my VoIP client to this machine and use it as a regular VoIP line? Ignore the security hardening (changing all the default passwords and ports 5060 for ex), blocking attacks with fail2ban and configuring a FQDN of the system (using maybe no-ip service) or using a VPN. The question I have is: can this ONE dongle serve as VoIP trunk AND Internet connection for calls and management (ssh + https) in the same time?

[@HOTKEY404]

@@dededobre I did a quick test and I established a ppp 3G connection and I made an outgoing connetion so it should be possible. Especially since they use a different ports: /dev/ttyUSB0 - internet, wvdial /dev/ttyUSB1 - asterisk, audio /dev/ttyUSB2 - asterisk, data

[@dededobre]

@@HOTKEY404 Thank you Thomas!

[@zabawymatyldy6501]

Uzupełnienie do poprzedniego wpisu: BTW - konfiguracja Outbound Routes jest raczej OK: Dial Patterns that will use this Route ZXXXXXXXX bo gdy w Route settings przelacze "Optional Destination on Congestion" z "Normal congestion" na Extensions i tu nr np. 15 to reguła działa. problem jest chyba w konfiguracji dongla. Dodam ze polaczenia przychodzace dzialaja poprawnie.

Dzien dobry! Thank you for your video. Your video is so helpful to me. I'm living in Poland. And I'm using Play network right now. It seems that you are using Virgin mobile in this video. And Virgin mobile is using play and you are connected to play gsm. I know that the transmitting mode depends on the modem, but have your modem connected to the 3G network? I want to use Play in 3G network on the chan_dongle. I will waiting for your answer. Miłego dnia!

[@HOTKEY404]

Hi. RasPBX uses automated process of switching the mode of your dongle (with usb_modeswitch). Are you using RasPBX or sth else? You should be able to find details of your modem with lsusb and you can search for it on the list asterisk-service.com/en_US/page/chan-dongle-modems to check compatibility - usually: the older = the better. And yes .... modems that I'm using are 3G only.

Dzięki za tutka. Jeżeli potrzebujesz pomysłu na następnego tutka, to proponuje "Bramka GSM (raspbx) jako trunk".
