VoIP One-way Audio and Voice drops
- 
 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?

 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

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.

 Tested that ping and did not see any errors. 
- 
 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.

 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.

 More ping data all started at about the same time for about the same length. VM Host 1 - Windows and Linux Server

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

- 
 Seems pretty unlikely to be Linux then if multiple, non-patched systems were impacted. 
- 
 From the Meraki GUI I can do a similar ping test. It shows no loss of packets and a 1-4ms response time. To the 204 IP address. 
- 
 What Linux is the "other" one?
