Hello,
I have around 600 AIR-AP1815W-E-K9 devices.
All of them got IP Telephone Grandstream connected to their Port 1 - POE.
All phones are added to Remote Lan "IPTEL" group in VLAN 200.
Works everything like it should.
I can see number of connected phones in Profile RL_iptel

after around 15 minutes, RL_iptel goes down to maybe couple of devices... and I cannot ping those phones.
But for those 15 minutes they are working, I can access their management, make calls...
Like they go to some kind of sleep mode? Or is there maybe some timeout period in Remote Lan settings that's putting down clients?
Thanks
