Performing firmware upgrade on Polycom vvx400 handset running 126.96.36.19927 to new firmware 188.8.131.526. 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?
welcome back to the Polycom Community.
I am not aware of any reports of this but most people do not set a VLAN address manually as there
are different ways to do this using LLDP, CDP or DHCP.
