VoIP One-way Audio and Voice drops

Wow, so now to track down the packet loss. If the desktops don't see it.... where is it coming from?

What is the packet loss when trying to hit your firewall? What about hitting the router on the other end of the WAN?

Is the PBX still running in Hyper-V?

It is, I don't have another option right now.

[scottalanmiller]

So no issues hitting the local firewall. Now the other wise of the WAN but still "local"?

You don't have a Broadcom NIC, by chance?

All Intel.

I really think it's related to the Hyper-V Nic Driver & Linux. Make sure the Hyper-V host has all windows updates installed. You could also Disable VMQ and Disable Large Send Offload Version 2

I moved to a different host last night. I disabled VMQ, not Large Send Offload though, I will look into that.

This is the WAN access IP address.

Tested that ping and did not see any errors.

[scottalanmiller]

Yup, testing from here and not seeing packet loss. Looks good at the WAN side, as far as the pure WAN link.

I've tested it from my house as well and it works fine. So that tells me it is something internal.

Have people had issues running a PBX on Hyper-V? I've heard about the linux driver issues that 2008 had, but I was fairly certain that those had been resolved.

[JaredBusch]

I run PBX in a Flash and Free PBX on Hyper-V no issues.

I have ran Elastix 2.4 as a demo on Hyper-V.

Are you running it as a Generation 1 or Generation 2 VM?

Generation 1

More ping data all started at about the same time for about the same length.

That really makes it seem like a driver or similar issue. Very weird.

[coliver]

I'm really concerned as to why it would pop up 5 months after the original deployment. Even if it were a driver issue. Could a Linux update have caused this?

[scottalanmiller]

A Linux update could have, of course. But were both of these systems patches recently? It is far more likely to be a HyperV issue. But either is certainly possible.
