No audio for another Quectel card

[shuenpin]

Hi,

I've installed three Quectel EC20 card on my freepbx.

I've edited the /etc/asterisk/quectel.conf and add [quectel1] and [quectel2] section on config file.

executed "aplay -L" command and had three usb audio card.

When I call via quecte11 or quectel2, this call didn't have audio and stuck "Dialing" state after hungup.

After remove two quectel card and everything is working fine.

Can you help me to solve this issue or this code don't support multiple quectel card?

Thank you.

Did you try with the correctly matched serial ports? You could try with only serial ports before moving on to using uac. Please show contents of your quectel conf file.

@IchthysMaranatha
I only use "uac" mode for audio.I'll try to use audio via serial port on another quectel card.

As per that file, only first dongle will work (maybe you've commented out after trying them together). And you shouldn't provide both audio port as well as uac. And your port-uac doesn't seem to be matched.

You need to identify correct data-audio port pair by first configuring just one of the cards using serial audio. Connect all cards but configure one by one individually. After properly identifying correct pairs, try configuring all together with serial audio. Then move onto uac.

[IchthysMaranatha]

There's also the question of system being able to manage the power draw. Without using asterisk (unload chan_quectel), are you able to place and receive calls simultaneously on all 3 devices with minicom?

I had use "ATD" & "ATA" via minicom, they are working fine.

When I dial number via FreePBX.
Still no audio and stuck Dial state after hungup.

[IchthysMaranatha]

Are all 3 working individually? For eg if you comment out quectel0 and quectel1 completely, is quectel2 working correctly?

This seems to be an urc issue, are you getting urc correctly on all data ports with minicom connected to ttyUSB3 ttyUSB11 and ttyUSB19? Is the ^dsci urc correctly shown when calling out or in?

[shuenpin]

@IchthysMaranatha
No, I comment out quectel0 and quectel1 , quectel2 still no audio and stuck Dial state after hungup.

ATD and ATA command working fine via minicom.

[IchthysMaranatha]

Then that modem is not working with chan_quectel. atd and ata are not sufficient, you need urc working as well. Put at^dsci=1 in minicom for working modem and non working modem. You will see urc coming through for the working one when calling in or out.

Run these commands to enable proper urc
AT+QINDCFG="all", 1
AT+QINDCFG="ring",1,1
AT+QINDCFG="smsincoming",1 ,1

[IchthysMaranatha]

urc will also not be received if data port is not correctly set. For eg normally with only 1 modem, 1 is the AT port and 2 is the audio port. 3 is the modem port which also accepts at commands but will not provide urc if urc is configured for AT port as is by default. Important point is whichever port is configured in quectel conf should be able to send at commands and should also receive urc. Once this is confirmed with minicom, it will work with chan_quectel as well.

[shuenpin]

@IchthysMaranatha

As your post, I had misconfig the AT port on quectel.conf.
Thank you for your reminder.

I'll try and update as soon as possible.

[shuenpin]

@IchthysMaranatha

I change the data port from wrong port to another port, the audio is working fine via serial port !!!!

@IchthysMaranatha

BTW, How can I identify the right AT command port on Quectel card?

Can you provide some method to identify ?

Thank you

[IchthysMaranatha]

Glad you've got it working. You can use discovery mode instead of specifying the ports. Just comment out everything else and write only values of imei or imsi for the 3 devices. The ports would be discovered automatically.

[tjjh89017]

Is URC conflict with UAC mode?
or those are different purpose config?

[IchthysMaranatha]

No, he hadn't got ports right, it will work for him now even after switching to uac. urc is needed, whichever mode is used. Auto discovery works only with serial audio.

[tjjh89017]

ok got it
tks a lot

[shuenpin]

@IchthysMaranatha
I also enable VoLTE on Quectel card successfully.

This is detail AT command & comment from official forum.

AT+QCFG=“ims”,1 //enable IMS (VoLTE)
AT+QMBNCFG=“autosel”,1 //enable auto selection of MBN file based on SIM IMSI
AT+CFUN=1,1 //reboot to take effect

[shuenpin]

@IchthysMaranatha

I switch audio from serial port to UAC mode.

The audio with three cards is working fine.

Thank you.

[hellkaim]

Could you may be point or briefly describe how you configured Asterisk and ALSA to utilize UAC?
My understanding is that I have to point Asterisk to the right sound device and change dialplan to point the call to it....
THX

[IchthysMaranatha]

Alsa is integrated now, no need for any alsa driver in asterisk or any asound config. Just follow this #2 , make needed changes in quectel.conf as specified

[hellkaim]

So even in Asterisk 13 I can just switch device to UAC and make no change to dialplan? I mean I can just point the call to quectelX device in _extensions.con_f and that is it? If so that is a real enabler.

[IchthysMaranatha]

Have not tested with v13, but should be working. quectel.conf should be correctly configured.
