I've read you shouldn't forward those ports unless absolutely necessary. It was working fine without them initially.
What's the logic on not forwarding them? If you restrict them to the IP(s) of the SIP Trunk provider there is no additional security risk but it always adds stability.
Doing it "only when needed" means you've knowingly left a fragility and are just waiting for things to fail before fixing it. That's not a best practice style guideline
Like saying "don't steer the car, until you start hitting small objects on the side of the road, THEN it is a good idea to steer."
That's fine. Either way I was still having that issue with the ports forwarded.

That's extremely odd. Have you tried connecting a PBX to the provider from another location? This really does sound like it is down to either the provider themselves or the ISP having an issue.

Now the question is, are all the needed ports fordwarded, and working as desired? I have found when setting up FTP I often forget to forward the data ports needed to work with FTP.

@coliver it is relatively easy to set STUN up on a phone at least and test that part.
On a side note, what is your PBX running in? I once tried running in Hyper-V and ran into a slew of problems with load and the NIC drivers.

His ISP is the SIP trunk provider for the main SIP service.
He setup a SIP trunk to another provider and experienced the same issues.
With all of the testing done to date, the problem is the ISP based on what we know so far.

Related: Hyper-V has NIC issues if you do not disabled VMQ on the VM unless the hardware supports it correctly. I have a client with Hyper-V 2012 R2 and a ton of NIC issues were going on until I disabled VMQ.

It is running on Hyper-V. Up until this point it hasn't been an issue.

Unlikely having VM related issues, but they are worth mentioning. The Hyper-V server was not updated lately was it?

I don't think so but I'm going to look into it now, I've looked before but didn't notice anything. I've noticed something odd, the PBX server has some serious packet loss to the SIP trunk whereas my desktop does not... they are both on the same switch. This still doesn't explain the issues I was having with the other SIP trunk but it may have something to do with the current issues.
-
@coliver have you checked to see if the NICs in your Hyper-V server actually have VMQ enabled or not?
In Powershell (assuming Server 2012 / R2) try
get-netadapter-vmq

Gotcha. Yes, that makes sense. I missed that the ISP and SIP trunk was the same provider.

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.

The Hyper-V team was the original network adapter that this was on. Since starting with these issues I have moved that over to a dedicated port Ethernet 2.

Have you considered disabling VMQ ?

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).
