Currently running OSCC V8 R2.16.218 on HiPath 4000 V6. All agents are using OpenStage 40 HFA (all running V3 R0.40.0 HFA 171020). Once in a while an extension will go out of service and back in a couple of minutes later. This will happen several times over the course of a few hours. If someone is logged into the phone, it will kick them out. If they're on the phone, the connection will stay up, but OSCC "loses" them. The only fix actions I've seen that work are to either: 1) Rebuild the extension completely in the 4K or 2) Restart OSCC. If anyone knows of a real fix for this, that would be super!

I'm running DLS V7R2 CV436. And after changing the gateway cards, I'm still seeing the problem once or twice a day.

Probably not relevant here but I have had issues with 35G handsets with Cisco PoE+ switches, in particular, 3850's.
They work fine on 3_R0_24 but have issues with 3_R0_30 (in the DERT software) and 3_R0_40 with the port network port flapping, H02, D02 and Hy2 errors. One phone would register but often wouldn't have dialtone.

I think one of the firmware revision added compatibility for HP Procurve PoE+ switches which I suspect is the culprit.

I actually got on a call with a CCIE from ATOS. Smart dude! We talked through a whole bunch of possible scenarios as to what could go wrong on the network - with our network engineer. We're going to have to Wireshark the switch ports of some of the phones to actually see what's going on. The behavior described is what happens when communication is lost on TCP port 4060. It's funny, though.... haven't had one drop in 4 days now. SMDH!

If you find out what makes it get lost I would love to hear it. I have no skills to be able to dive that deep, and the kiddies that run the network don't have a clue....
