so the problem is which one is the audio path
ttyUSB0-4, which one
hi, carlos
I am also using asterisk with freepbx on my raspberrypi for a few years, but my USB dongles are from Huawei and all of them are 3G/2G mode. They are working well on CS.
You know GSM/wcdma is getting old, some countries have stopped 2g, this is the reason why i want to change them to VoLTE
I know VoLTE is supported on quectel ec25/ec20, but using on asterisk-chan-dongle, it shows “voice support NO”
*CLI> dongle show device state dongle0
-------------- Status -------------
Device : dongle0
State : Free
Audio : /dev/ttyUSB1
Data : /dev/ttyUSB2
Voice : No
SMS : Yes
Manufacturer : Quectel
Model : EC20F
If you have any update, just write here
thanks
It means Audio goes to ttyUSB1
Yes, correct. Thanks!
Good morning from Brazil.
The success I had was just receiving the audio from the person who i talking , but the uploading of sound from my microphone, did not work, through the serial interface.
I am studying how to make the dialing code in python to test 100% both sides of the call sound through the usb interface, if you want to talk, call me on telegram @Casantoslopes.
hi Carlos,
how about your trail
As you not updating your code, Carlos, i did make new try and its here:
its including patches of ca4ti and others, but code taken more fresh from wdoekes.
and driver i compiled for openwrt-18.06
try and let me know please, ty. surely its not final yet, so needs your feedback!
@pl4sm0nk /spacedream
Please let us know how far you’ve got it working. Do you receive audio both ways on volte calls in asterisk?
