I installed a new Freepbx 13 box at a clients and the are noticing a strange issue and it’s very intermittent. They will be in the middle of a call and it will just drop. They said they can either be talking to someone on a cell phone or land line when it will happen so it’s not like we can easily blame it other side being a cell phone.
Today was the first time I ever experienced it calling them. I called the office and the receptionist picked up I was on the phone with her for about 5 secs and then it went dead. Because of this I was actually able to look at the logs to see what happened and it looks like the phone system is getting a hangup command from some where when it does it. The phone call in question got a hangup cause: 16. Which my understanding is just a standard hangup.
Could the phone system randomly be issuing this command or is it more likely that it’s the phones doing it. I grabbed a section of the log files if you would like to see it.
And to give a little back ground they are running Freepbx 188.8.131.52 and Yealink T-46s phones. This issue doesn’t seem to be isolated to a single phone either.
