Customer is running a MiVoice Office 250 (Mitel 5000) V6.0 and we are having problems with multiple PKM's.

They are currently connected to digital 8568 sets. The customer complains that they have to re-boot them constantly and some times they do not come back at all. We've replaced the units themselves, the phones, and the power supplies but the problem persists.

Anyone ever seen anything similar? I'm at a loss.

Thanks
