GSM VoIP Gateway with Chan_dongle

A highly affordable GSM VoIP gateway can be obtained using Huawei E155X or compatible USB modems and chan_dongle, providing both inbound and outbound calls on GSM/3G networks.

Hardware requirements

Chan_dongle is able to work with many different USB modems from Huawei, such as K3715, E169 / K3520, E155X, E175X, K3765 and others. Read the full compatibility list here.
Before connecting the modem to your RPi, be sure to use a power supply rated at least 1A, better 1.2A or more. If your power supply does not provide enough current to power both the RPi and the modem, you can get problems booting the RPi, or calls to/from the GSM network fail with error “dongle disconnected”.
Alternatively a powered USB hub can be used as well. If you want to use 2 modems, an additional WiFi connection or other devices that require considerable amount of current, a powered USB hub is absolutely required.
In case you are using one of the older 256MB models with F1 and F2 still in place, you might want to consider bridging over F1 and F2, read more details here. This is however not required on the newer 512MB models, or when using a powered USB hub.

Not all Huawei USB modems work out of the box, on some of them voice calling capability has to be enabled first, some need to be upgraded with the latest firmware. Details on this can be found on the original chan_dongle wiki.
Before inserting the SIM into your modem please deactivate the PIN on your card. This can be done with any phone. Insert the SIM into your phone, deactivate PIN and you’re done. You can also use the Mobile Partner software – which comes with the modem itself – on a Windows computer to do this.

Setup and configuration

Once your modem has PIN deactivated, latest firmware and voice enabled, run this command:

 install-dongle

This installer script installs chan_dongle.so, and creates an initial configuration. The script is provided with upgrade #11 (and improved further with upgrade #12). Once the installer has finished, connect your modem to the RPi. If it was connected already before, unplug it now and plug it in again. Some older modems still require usb_modeswitch to enable data/audio mode, for those a complete reboot of the RPi is recommended at this point.

Then log into FreePBX, in Connectivity – Trunks click Add Custom Trunk. Provide a trunk name, set Outbound CallerID to the number of your SIM, and enter in the field Custom Dial String:

dongle/dongle0/$OUTNUM$

Add an outbound route to use this trunk, as well as an incoming route. On the incoming route set DID Number to your SIM number, precisely matching the number you entered when running the install-dongle script.

More details on how to setup inbound and outbound routes can be found in the forum.

Sending and receiving SMS

The install-dongle script provides a few basic options to send and receive SMS. Received messages can be forwarded by email. If no email address is specified, messages are stored in /var/log/asterisk/sms.txt instead.
Additionally, received messages can optionally be forwarded to a mobile phone number on top of sending them by email. This is done through the first dongle0, your mobile operator’s charges apply for sending SMS.
In order to send out custom messages, a password protected web page can be activated during the install-dongle run. This page is located at http://raspbx/sms or http://raspbx.local/sms (for Mac).
A web page for sending USSDs is optionally available. Install it with:

apt-get install ussd-webpage

The page can be found at http://raspbx/ussd or http://raspbx.local/ussd (for Mac).

Troubleshooting

If it doesn’t work at this point, at first check if the interfaces of your modem match the configuration:

ls -l /dev/tty*

2 devices, ttyUSB1 and ttyUSB2 should show up. If the numbers are different, something like ttyUSB0 and ttyUSB1, edit /etc/asterisk/dongle.conf and change the values below [dongle0] accordingly.
Many modems require the usb_modeswitch program to switch over from CD-drive mode (for installing Windows drivers) to modem mode. The /dev/ttyUSB devices will not appear before the switch-over was done. Make sure to have all the latest upgrades on recent Debian Jessie based images to fix some initial bugs with usb_modeswitch. If your modem is still not switching it might be necessary to add a custom rule for usb_modeswitch.

Some users have reported voice calling with a specific mobile operator was not working, while using a sim card from a different provider with the same modem and RPi worked perfectly fine.

Troubleshooting power problems
In case the modem devices ttyUSB1 and ttyUSB2 are disappearing as soon as a call is set up (or also at other times), and later they appear again, it is most likely the modem is not sufficiently powered and thus disconnects again and again. Try these options:

Remove any USB extension cord from the modem and connect it directly.
In case a powered USB hub is used, try a different one or even try without it. With some of those hubs the modems just don’t work properly, although the current rating of the hub’s power supply is high enough.
If the modem is directly connected to the RPi (without a hub), the power supply has to power them both. Try different power supplies, as some have problems to keep their output voltage stable under higher load.
As a last resort, you can also try to use a different modem.

For more information, read the complete documentation here:

https://github.com/bg111/asterisk-chan-dongle/wiki

Modems reported working/not working

On top of the compatibility list on the original chan_dongle wiki, users of RasPBX have reported several modems to work fine with the RPi:

E153
E1550
E1552
E156G
E160
EG162
E166
E169
E171
E173 (some types of E173 seem to not work, only E173 with Qualcomm chipsets do work)
E1750
E180
E303
K3520 (not to confuse with K3520-z)
K3715
K3765a

The following modems had issues and could not me made working so far. Please let us know if they work for you nonetheless:

E150
E1752
E303C
E352
K3520-z

  Unfortunately neither SMS nor USSD works with German umlauts or other special characters. This is a bug in the message decoding functions of chan_dongle.

Just in case someone else has problems dialing numbers (from a sip endpoint) that start with a +XX (eg +49) instead of your local number (because the GSM endpoint doesn’t like them):

Edit /etc/asterisk/extensions_custom.conf and add the following to the end of the file:

[outrt-1]
;convert +49 numbers to start with 0
exten => _+49X.,1,Macro(user-callerid,LIMIT,EXTERNAL,)
exten => _+49X.,n,Set(MOHCLASS=${IF($[“${MOHCLASS}”=””]?default:${MOHCLASS})})
exten => _+49X.,n,Set(_NODEST=)
;exten => _+49X.,n,Noop,testblaaaa

exten => _+49X.,n,Macro(dialout-trunk,2,0${EXTEN:3},,off)
exten => _+49X.,n,Macro(outisbusy,)

Basically this is copied from extensions_additional.conf and all ${EXTEN} replaced by 0${EXTEN:3} or whatever your local standard might be.

Hi I have finally managed to get GSM gateway working on raspbx. I had a Vodafone K3565 dongle (not K3565Z, that won’t work, has to be Huawei one), and found it’s a rebranded E160.

    When you plug in the modem after the Pi is booted up do you still need the command or will it then switch over automatically?

Hi guys,
I am going though problems with huawei E169,
the dongle is detected successfully on Raspbx, SMS is being routed to any other mobile number with no issues, but the voice calling is not working. for some reasons. when I call the number it goes to voice mail straight away.

I connected to modem to a window machine in order to use DC unlocker to check if voice is enabled, and it was indeed activated.

on the RPI I created custom trunk, created sip account, and create route.

but ll this is not taking me anyway. any help is hightly appreciated.

Dear experts,

Kindly , I need your support regarding strange issue I face with my HUAWEI 3G USB modem Model E173, which support voice calls. When I use your software , mobile partner and make phone calls to another mobile phone , I hear voice clearly into my laptop speakers. But when the mobile phone user on the other side pushes any mobile Phone keypad , I can “NOT” hear DTMF tone into my laptop speakers.
I went to another place (40 kilometer away) , and run Mobile Partner again , now when I call the same mobile Phone , I can hear the DTMF tone when the Mobile phone user clicks any of the keypad. Is this related to device configuration. Which AT command and settings I use to make the device able to receive DTMF tone.

Thanks so much for your support.

For those suffering the constant disconnect I found the solution at the bottom of this post to work perfectly:

https://code.google.com/p/asterisk-chan-dongle/issues/detail?id=137

I am using a E173L (VTR Chile). It was unlocked and voice was enabled.

  What model E173L do you have? I’ve got a E173Ls-5 and my outgoing calling is working but my unit doesn’t receive incoming calls.

Hi,

I’ve got a stupid question. :S
When you’re taking about the SIM number here:
“On the incoming route set DID Number to your SIM number, precisely matching the number you entered when running the install-dongle script.”
Then you are talking about the mobile phone number, right?

Best regards
Camillo

  Alright, my dongle had voice disabled, despite DC Unlocker showed enabled most of the time. – Faced that issue with a E1550 by 3 AT.

I bought a Huawei 169 and it didn’t have a SIM in it. What would be a good provider to do pre-paid to connect to SIP provider? I really only want to do for testing and would be used as a back if my internet went down. Its for home use only so only a couple users would be using the system. I really only wan to pay a 1 time fee, and renew as needed so no re-occurring.
Thanks!

Can somebody help me, i have installed chan_dongle, everything works perfect (in/out) but now i want a disa with pin, but i cannot get a pin in, everytime pin incorrect. Seems it doesn’t recognize my pressing.
if i get on the same disa via landline (SPA3000) it works perfect, gets the pin and continues. But over GSM Stick with different mobile phones it doesnt work. No inputs works… How to get this done?

  You could experiment with the dtmf= option in /etc/asterisk/dongle.conf. Maybe a different setting than the default works for you.

Hi all,

Just wondering how I would go about adding a second dongle to my Pi? I am not sure how to install the second one??

Any help would be appreciated.

Cheers!

  First of all you need to have a powered USB hub for both dongles. Unfortunately not all of these hubs are working well enough, maybe you need to try a few. Then install the first dongle according to the description. For the second dongle, edit /etc/asterisk/dongle.conf, copy everything below [dongle0] and name these settings [dongle1]. Then insert the correct ttyUSB devices for audio and data in section [dongle1]. You might need to set the subscriber number in your dongles, please refer to the original documentation at wiki.e1550.mobi how to do this.

Got the E156G running fine.
No AT commands will enable voice, I had to use dc-unlocker, which worked Perfectly, instantly!
Works on 3 (Three) network in UK, not tried others. SMS also works without needing unlock, not tried USSD yet.

E169 works just fine with this setup. Can make/receive calls using AT&T sim in USA.

  Can you tell me where you bought the E169. I see there are some variants which don’t support voice. Thanks.

I am interested in using GSM gateway and huawei e173 to terminate calls to mobile phones. I need 24 channels running 100 percent operation including all the router, powerbar, battery backup, laptop and cellphone.
