Post your error logs in pastebin... and if your terminal settings are correct, you'd notice that some of the error messages are in red. In a mail just share that part, and rest of the full log in pastebin as suggested. Let me see if I can figure out anything... though don't be too hopeful.

Yes I am trying to use FS for IVR. You are right not many rather hardly have i seen on this community who are using mod_gsmopen. I wrote to the person who has contributed mod_gsmopen to FS but also no reply from his end too. I was looking for someone who could help me with this aspect of FS and then yesterday i came across your mail. I thought you would help me with mod_gsmopen. May i expect some help ?

Looks like, not many people use mod_gsmopen. I've opened a JIRA ticket for some minor issues in the Wiki, but hasn't been acknowledged, and I see no one responding this mail either. I'd seen your other mails in the archive while searching for hints in previous exchanges.

Ubuntu/Debian setups should be fairly similar. Did you follow the wiki to build it from scratch or using the repo packages ? I guess the former, because Debian repo packages didn't have mod_gsmopen.

I plan to spend a day or two reading about FS. The wiki has a tonne of info but not in a very well organized fashion. Also, I saw that the JIRA bug reports have lot of useful information in them.

BTW what are you trying to do with FS ? Set up an IVR ?

Hi jayanth
Since you are the first person whom i have seen working with mod_gsmopen. Can you help me with the ways to enable freeswitch use mod_gsmopen on ubuntu machine.
This may sound ironical that i am not answering your question rather asking a question as a reply of your question.
I will send you the error log which i come across after loading mod_gsmopen on freeswitch.
Hope we can together help each other.

Latest FS (Git HEAD, as of yesterday), cloned and built successfully with mod_gsmopen. Have used a fully unlocked E1550 dongle (tested in Mobile Partner softeware in Windows, able to make calls, send SMSs). Started FS with default configurations, as per Wiki instructions. Using the default configration for gsmopen as well (maybe, that is the problem) ???

I get the highlighted errors, while loading mod_gsmopen ! My naive interpretation (started with FS yesterday, and no experience with Asterisk either), is that in the gsmopen module default config, I find:

  <per_interface_settings>
    <interface id="1" name="gsm01">
      <param name="controldevice_name" value="/dev/ttyUSB3"/>
      <param name="controldevice_audio_name" value="/dev/ttyUSB2"/>

However from the error logs printed in FS console, I see:

4a3d1a0|4a3d1a0[(nil)|37     ][NOTICA  3056 ][none      ][-1,-1,-1] f.tty_data_device = |/dev/ttyUSB2|

Probably that is autodetected !! But how, without the IMSI/IMEI being specified?

With this understanding, I went ahead and modified the gsmopen config file, to:
  <per_interface_settings>
    <interface id="1" name="gsm01">
      <param name="controldevice_name" value="/dev/ttyUSB2"/>
      <param name="controldevice_audio_name" value="/dev/ttyUSB1"/>

then unloaded mod_gsmopen, and reloaded it, but now, I get this error:

2013-08-22 23:41:43.587104 [ERR] gsmopen_protocol.cpp:137 rev 4a3d1a0|4a3d1a0[(nil)|37     ][ERRORA  137  ][gsm01     ][-1, 0, 0] port /dev/ttyUSB3, NOT open

What does it need /dev/ttyUSB3 for ?

Maybe -- after all, my non linear progression into setting up FS and using it by somewhat of trial-n-error isn't helping!

thanks,

Jay
