Extensions Unregistering and re-registerin every hour or so.

[leo777]

Hello,
I have been experiencing a very strange behavior with 3CX for the past two days; extensions such as DialCode, SP3, SP5,SP7, and all of my 22 phone extensions, are unregistering and re-registering on their own every hour of so. In addition, calls are breaking up, and digital receptionist does not work properly. I have noticed that accessing the web interface takes longer then usual now, in many cases, I can't even access it. I have rebooted the server (Which is a virtual host, running on Hyper V stand Alone server), and I also noticed that all 3cx services needed to be started manually, there is also a delays of about 5 seconds when making a call, or when a call hits the 3CX server.

Any help will be greatly appreciated, or if there is another post that addresses this same issue, please point me to it.

Thanks,
in advance for your help.

Re: Extensions Unregistering and re-registerin every hour or

I really do not see anything in the log that shows an issue. I show a call coming in and being handled quite quickly (under 1 sec.). Some of what you describe is more typical of a congested network, and/or perhaps a processor that may be struggling. Do extension to extension calls have the audio breakup?

When I indicate a congested network, that is to say a network that does not allow the packets to flow "freely". It could indeed be that traffic is flooding in or that you may have a defective NIC, switch. router or firewall (software or hardward) that needs looking into. Maybe a setting was changed. If it is really bad, this could explain some of the phones having registration issues, but I am uncertain why the parking spaces would.

Look at the perfomance tab on your task manager and assess what it sees. Also look at the 3CX server event log (not the activity) and see if it provides additional detail and you may also need to check the event viewer.
