I am having some similar issues with CP-8821 phones. We get delayed rings meaning the LAN phones will ring and not the wireless. There is a lag from 15-30 seconds before it will ring on the 8821's after someone picks up the phone on the LAN phone. If no one picks up it may or may not ring. Definitely a high latency issue. When I ping from the Meraki dashboard I get a latency about 200ms vs. ping the AP from my desktop I get 1ms. It almost seems like the 8821 is in a sleep mode but it is not. We had the 7925 phones but they did not play nice with Meraki Any assistance with this would be appreciated. Going to open up a ticket with Meraki now and see what they say. AP=CW9164i Phone firmware=sip8821.11-0-6sr6-2 CM Version 14.0.1
