We have 4 of these phones connecting to 2600i AP's on a WLC. They can sit idle for hours, but when you make a call, it will work, then at random, just drop off and reboot. I also noticed that response times to all 4 phones will be good, around 30-40 ms then skyrocket after a while to upwards of 600 ms. I dont know if this is normal, and happens when the phone is idle, but I did notice when calling extension to extension between 2 phones response times were normal.
When the call drops, ping stops responding.
I have done quite a few deployments, and can find nothing wrong on the WLC or callmanager, this is a first I have ever seen this. Not sure if its a bug on the WLC, or the phone.
