Performing firmware upgrade on Polycom vvx400 handset running 5.4.4.4727 to new firmware 5.4.7.1696. The phone fails to acquire network IP address and register after downloading the new application and when checked we found the vlan id was cleared. Note the vlan id is manually set. I see same issue was fixed a few firmware versions back in bug VOIP-100191. Could the issue still persist. Has any one seen this issue in newer firmware?
