That is the same version I’m running. I have a case open with 2n but they can’t figure it out.  My customer is very unhappy. I called Cisco and they took a capture on their end showing the silo is issuing deregistration commands.  On the solo side it...

Check to make sure DNS is working

2N Solo video intercom not staying registered to Webex calling.  I can register the device just fine but a few hours later the device deregisters with WxC.  A reboot of the device registers just fine.  A viscous cycle.  Anyone else experience this?

I have gotten my solo to register but having a hard time keeping it registered…every time it unregistered I cycle the switch port to reboot and comes right back…until the next 3 hours or so when it unregistered again

I understand that Cisco is supposed to come out with Voicemail as a service sometime this month to satisfy this requirement.
