VoIP One-way Audio and Voice drops
-
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?

CentOS 6.6 final. FreePBX runs on CentOS 6.5 final.
This is one running OpenSuse
-
Does a Windows VM on the hyper-V server have the same issue?
Also what about a UEFI linux running in a Generation 2 Hyper-V VM? -
Ping results from the Meraki. All of these are on different ports of the Meraki.
.88 is my deskphone, .121 is the PBX and .116 is a Windows server.

That doesn't make sense your out bound pings where fine on the other devices with no issues.

Yep, that was pinging the same windows server that had pinged it before. I'm going to try a few different phones and PCs around the network to test this.

So even the deskphone is losing a lot of packets? That's very, very fishy. Maybe there is a switch issue or something?

I moved the phone I was testing with off a dumb switch I was using and it is now directly attached to the firewall.
.215 is a PC attached to a different switch, which is directly attached the firewall. The Hyper-V host that the PBX resides on is directly attached as well. The other host goes through a switch.
-
That's a lot of drops for a LAN. Should basically be zero.

It just seems to be the firewall. Pinging anything on a different switch through the firewall results in 0ms response (or less than 1). Which brings it back to maybe the firewall isn't working correctly?

The Meraki? I'm not surprised. Their router/firewalls are underpowered.

But didn't the issue exist with the Ubiquiti too, which should be orders of magnitude more powerful.

I know ping isn't the best indicator but it really is the best I have at the moment. Here are two captures taken at almost the same time:
PBX
Meraki
-
Here is the PBX pinging both the Meraki and the remote switch at the same time.
Meraki
Remote Access Switch
-
Sorry, the remote switch is "through" the Meraki?

Yes, switch isn't the right term. It is the access to the rest of the internet.

I think he Means Phone Switch.. As in sip provider.
-
I think I agree with Scott.. I wonder if you have a failing switch. Can you replace it.. or for starters.. move the meraki to a different port on that switch?
