Hello all,
My company is experiencing an odd issue. We only us the meeting rooms once per week for our weekly management meeting and the last 3 times we have tried logging into them (last three weeks, every Tuesday) you are immediately dropped after connecting to the room. All other phone calls work fine, incoming and outgoing, transfering, etc…
Restarting dahdi, asterisk, and rebooting the machine do not fix anything. The only thing that I have found that “fixes” the issue is that I have to reinstall dahdi. All the dahdi files are still in the machine, i just navigate to usr/src/asterisk/dahdi-linux-complete-VERSION and make install, restart the dahdi service and we are back in business.
The thing here is that I have NO IDEA what is causing this to happen…I have looked at a few log files trying to grep words that I think might hit on something but so far I have got nothing. I would really appreciate if someone could tell me where I might want to look for an idea of what is going wrong, it is almost as if the modules are uninstalling themselves or something because if I try and restart the service when it is NOT working, the “loading hardware modules” step does not give OK’s
I have tried researching forums for the CAUSE of the issue and have been unable to find anyone even talking about that, the two places I found just recommended re-installing Dahdi and the discussion stopped there.
I have attached the code from the moment I dialed our conference room extension, to the moment it hangs up on me. If anyone needs any logs, or for me to provide any additional info I would be more then happy too. I am fairly new to helping administer Asterisk and this is the first real issue that my boss has had me look into alone. I feel it is almost a try-out 
Thank You,
Jim
