Cisco VoIP Handsets Un-Register After Settings Change
I have a stack of 4 MS425's at the core of my network doing all my layer 3 routing. At the edge I have a mix of mostly traditional Cisco switches with some MS350's starting to get mixed in. We have a Cisco VoIP system that we host on-prem. The other day I had to create some additional layer 3 interfaces on the core stack and I noticed that while doing this, all of our VoIP handsets drop their connection to call manger (display goes blank for a couple seconds, phone shows "registering" then comes back to life). We are running 9.36 on all of the Meraki switches. Any ideas what is going on here?

I've definitely noticed that when adding layer 3 interfaces to a stack the other switches have to sync the config. But I haven't noticed the interruption. Is the L3 stuff you are working on in the same subnets as your phone/voice VLANs or completely separate?
