Periodicly I have issues moving phones from floor to floor at my site. Each floor has a different DHCP scope. To get the phones to grab a new address I have to wipe out the current settings and enter a static IP. Reboot and swipe again and set it back to automatic DHCP settings and then the phone will grab an IP and work. Has anyone seen this before? I'm on 5.0 using firmware 0624C6N on my 1100 series sets.
