I have 2 IPOffice Switches hooked up on my network in 2 buildings. They are connected over our network via bana circuits (copper lines that emulate ethernet). The one switch keeps dropping/locking up. I show no errors it justs drops and you can't see the switch. The only way to fix it is a reboot. It happened 3 times today already and 3 times yesterday. The system has been up almost a month. Outbound telephone still works however interoffice and voicemail do not because the voicemail is in the other site.
