MX Success Story: How Meraki helped our phones

[Mr_IT_Guy]

In our organizaition, we use Digium phones for VoIP. Prior to our use of Meraki, we were using a combination of Cisco and Ubiquiti routers. In one of the major updates to the phone system, the packet size increase and our routers were having an issue processing the packets at times, which caused all initial phone calls to fail the first time. After a redial, the phone would be fine for like 5 minutes. We did everything we could and even worked with Ubiquiti engineers to try to solve the issue, but no dice. When we brought in Meraki, the issue disappeared instantaneously. This solved a major headache for our users and our Telephony admin. This is just one of the many ways Meraki helped our organization.

good story bro

I'm curious as to how did you isolate the problem to be the packet size and how did you know that Meraki would fix the issue?

Great question @RobC. 

We were receiving calls from our users saying their initial calls would fail and they would have to redial  the number and it would work. We then took a packet capture and it showed that the "Do not fragment" bit was turned on. For some reason, the Ubiquiti EdgeRouter Lites we were using were having a hard time processing the packet and so the initial call would fail. 

We did not know if Meraki would've fixed our issue at first. This issue happened around the same time we were doing our trial of Meraki gear. We deployed the gear at a PBX site and a branch location and tested phone calls. When the issue did not occur, we got more test gear and tried more users making calls. When the issue did not occur, we knew it was a packet handling issue and that Meraki could handle it.
