I've seen a lot of issues from those "ISP as SIP trunk providers." Those seem to always be the ones that are willing to have things fail because they have good lock-in.
If you can test the third party SIP provider from home, for example, with the same setup (a bit of work) that would prove a lot.
I will bring my phone (the one attached to the Vitelity trunk) home and test it out there. I use a different ISP at my house. Or maybe I should bring it down to my parents who have the same ISP that would allow me to test that out the same network at least.

I do get this error: Networking driver in PBX loaded but has a different version from the server. Server version 4.0 Client version 3.2 (Virtual machine ID 82638176-8888-46C2-8FF4-6182BA79215C). The device will work, but this is an unsupported configuration. This means that technical support will not be provided until this problem is resolved. To fix this problem, upgrade the integration services. To upgrade, connect to the virtual machine and select Insert Integration Services Setup Disk from the Action menu.
But from what I've read this shouldn't cause any issues with actual connectivity.

Likely means it's suffering performance hit as the NIC might not be fully virtualized.

Ok, I will see if there is an update available for that version of Linux.

yeah, I would say this could be your whole problem (only the fact that SIP directly to a phone still had the same problem tells us it's not this error that's likely the problem).

@coliver I have read that a lot of NIC drivers do the VMQ implementation poorly in drivers which can kill performance, so I usually disable it, just to be safe. Most notably, this problem is especially prevalent on the Broadcom chipsets... I see you have intel.
It may be worth a shot, but there will be a brief blip if you use the powershell command to disable VMQ.
get-help VMQ
will list the commands.
get-netadaptervmq|where {$_.Name -eq 'NIC1'}|disable-netadaptervmq
Just replace NIC1 with whichever NIC is currently running your PBX VM.

This was the issue I had. Poor performance. and it was a Dell server with Braodcom chipset.

His VM is not the problem because a PHONE with the credentials directly entered has the same problem.

lol maybe the brackets around the second part of my statement made it invisible? lol

It is obviously a load issue. After ~3-4 pm I no longer see any issues. During the weekend I also saw no issues.

IBM server with Intel NICs.

Just in case I've updated the integration services for Linux.
-
Moving the VM to my lab server, trying to see if maybe that will resolve it. Currently nothing is running on the lab server. Wishful thinking I know but worth a shot.

Try your phone again directly to the SIP trunk.

I will tomorrow when the issues start up again. Right now everything is working as expected.

A network load issue. Maybe on the ISP's end? It could be, while unlikely, that RTP traffic is being completely dropped under saturation, kind of like inverted QoS.

I thought that I read that that was tested already?

I tested a third party SIP Trunk. Haven't done that with the ISP trunk yet.

Ah, okay. Thanks.
