Closed CpServiceSpb closed 8 months ago

Quectel channel with Asterisk 20.4.0 on Ubuntu 22.04 x64 LTS. Sound over serial ttyUSB is used. After AT+CFUN=1,1 (reboot the device) both-sides sounds was appeared, but error is remained: src/channel.c:135 channel_request: Asked to get a channel of unsupported format '(slin16)'

And there is echo. I tried to set "slin16" option to on/off or to disable it. Nothing changed.

With sound set up to UAC, thtere is no echo, but one way sound.

This is not an error but warning. You may safely ignore this message. slin16 option is for SimCom modules only.

See also my wiki page: Improving audio quality.

Which side is available in UAC mode? What module are you using?

CpServiceSpb commented 10 months ago

Now there is no voice from inside to outside. It doesn' t matter who is call initiator. Module is EC25-E.

From modem to Asterisk or from modem to GSM network?

You can try to diagnose this problem in UAC mode by setting high debug level (6,7 and 8):

core set debug 6

This generates a lot of messages. Look for messages with [ALSA] ([ALSA][CAPTURE], [ALSA][PLAYBACK]) string.

You may also rebuild chan_quectel with the latest changes. But these changes brings JSON-formatted variables so be careful.

Now there is no voice from inside to outside. From internal phone to external ellular station (phone) .

You can try to diagnose this problem in UAC mode by setting high debug level (6,7 and 8): Ok. I will try.`
