FreePBX - Endpoints unregister

Hi

Running FreePBX 13.0.192.19 and using Grandstream phones (latest firmware).  Intermittently (one or twice a week), our phones lose the ability to make calls, either inbound,outbound, or internal.  While the trunks remain registered, all of the endpoints report as being Unreachable.  this condition remains until I restart the FreePBX server.  When this happens there is no issues with the underlying network connections, and there is no firewall between the IP phones and the FreePBX server.  Would anyone be kind enough to point me in the right direction on this one?

Have you tried to use a different phone or a soft phone to see if the issue is caused by the PBX not by the phone ? If you try one of them and waited until the next time the phones gets disconnected u'll be able to judge where exactly the culprit is .. and then you'll know if it's a PBX bug or a the phones.

How are the phones registered btw? Are they directly connected over lan or behind a firewall ?

The issue happens on multiple phones at once. Even incoming calls to the IVR stop working (three short beeps and the call disconnects).  The PBX and IP phones are on the same network with no firewall in between
Do you see anything on the FreePBX logs? This is obviously a PBX issue not phones so you need to dig there.
On FreePBX community they usually share issues like this which might be common since it could be a bug. try to look there if your issue has been reported before.
Do me a favor, when that happen again do not reboot the server but instead disable the firewall and tell me if the problem still persisting.
Maybe those phones are getting banned because a bad registration. Also, if you are using pjsip keep in mind you are using the port 5060. I dont know why freepbx set them up that way.
