Hi community, I'm hoping I can get somewhere here as I've been unable to work through this with tier 1 & 2 support. My company migrated from Office@Hand to Ringcentral a week ago, and almost immediately after the account was moved all of our Cisco SPA303 phones, purchased through Office@Hand/Ringcentral have started to drop their registration. We've made every single requested change to our Palo Alto systems in 3 locations, and looking at the IP of each phone we can't find a single denied, blocked or dropped entry from any of them to any outside IP. Yet, each affected phone will drop registration for 30-40 minutes and then come back online. It seems to randomly happen through the entire list of phones and never quits. This only began after the account was migrated to Ringcentral, it never happened before and does not happen on another companies account I manage that has yet to migrate.
On an existing phone, both offline and online we see traffic from it to 104.245.57.131 on port 5090.
On a phone deployed post migration we see traffic from it to 199.255.120.146 on port 5090 and that phone never goes offline.
Any ideas where else I can look?
