[Freeswitch-users] Unable to get K3765 dongle signalling using mod_gsmopen

[Silviu CHINGARU]

Thank you for your reply.

Can you give me a small example of usage of minicom with dongles? Baud rate, etc...

Should I call only from minicom via AT commands sent to interface or use freeswitch to init the call and only sniff the interface with minicom.

Sorry if is noob question but I never tryed those low level commands.

Hi!

You should try other ttyUSBx. One of ttyUSBx used for commands only, but another for commands AND signalling too.
You can open ttyUSBx with minicom and make call to number of SIM card inserted to modem.
If you will see RING you will find "right" serial port.

Best wishes,
 Dmitry.

Hi,

I'm trying to make mod_gsmopen work with my testing freeswitch. I have the following setup:
K3765 Huawei dongle
Freeswitch 1.2.9 with mod_gsmopen

I setup a gateway using gsmopen.conf.xml (see attached) and an extension in dialplan. I've set consolelog 9 and I'm able to make call via mod_gsmopen from any switch phone, but the signaling is not working. So when I answer to mobile called by gsmopen module, sip phone is still displaying "Conecting...", I can talk to mobile phone via sip phone and reverse but when I close the conversation from mobile side is still "Conecting...".

In console I don't see any signaling from gsmopen like ringing, answered and so on.

I think the serial interface is ok because I can send AT commands to init the call but I don't get any signaling. Also the audio interface is ok because I have audio both sides (via Early Media because the call is never signaled as answered).

I've attached:
- reload.log (output from freeswitch when I type reload mod_gsmopen)
- call.log (output from freeswitch when I init the call via mod_gsmopen)
- gsmopen.conf.xml
(I've changed / masked context, ip and phone number for privacy)


I've used this dongle also with chan_dongle in asterisk and was working fine but on freeswitch I'm unable to configure it.

Please help, I don't even know what to read! What could be the problem, what is wrong? How can I figure out what is wrong? Thank you very much for your time!

Best regards,
Fiftyz
