Too little info. I can't deduce any cause from these error messages alone.

If I disable or remove audio=/dev/...... data=/dev/...... and add or enable imei = ............... I will not my dongle connected to dongle chan. That is dongle show devices is empty.

When you start asterisk without any dongle configured, you can search for a device with this command:

Asterisk *CLI> dongle discovery 
; discovered device
[dc_0177_0724](defaults)
;audio=/dev/ttyUSB1
;data=/dev/ttyUSB2
imei=35921103712xxxx
imsi=72234124377xxxx

As you can see, there is "imei" but "imsi" is important too. Those lines show a common configuration for dongle.conf. Showing the actual ttyUSB# used by audio and data.

You need to put both lines in your dongle.conf

Best regards.

How is to specify /dev/............. ? I reassigned /dev/ttyUSB9 to /dev/devModem. Even not /dev/ttyUSB1. But dongle discovery requests /dev/ttyUSB1 only. The error message is: at_read.c:101 at_read: [/dev/ttyUSB1] at cmd receive buffer overflow pdiscovery.c:565 pdiscovery_do_cmd: [MyHuawei discovery] read from /dev/ttyUSB1 failed: Inappropriate ioctl for device

I knew imei and imsi through minicom, specified it at dongle.conf and noone dongle appeared by 'dongle show devices' . More correctly,device from dongle.conf is shown but as not connected.

Post the output of this commands (as root):

• lsusb
• asterisk -rx "dongle show devices"
• asterisk -rx "dongle discovery"
• cat /etc/asterisk/dongle.conf

best regards.

Ok, dongle discovery only show new and unconfigured modems at your server.

Please do this:

1. Edit dongle.conf and comment audio and data lines (the last two lines of this)
2. restart asterisk
3. check "asterisk -rx "dongle show devices". You need to see this empty
4. Then run "asterisk -rx "dongle discovery" and you will see your IMEI and IMSI.

Best regards.
