I have a few Trio 8800s that refuse to use the VLAN advertised in LLDP as the "voice" VLAN. They continue to use the untagged data VLAN. I think this related to a check the Trio's software is doing to see if the voice VLAN is different from the PVID. Per another post, if they are equal the Trio will continue with untagged operations. The LLDP packets from the switch seem to incorrectly indicate the PVID is the same VLAN as the voice VLAN. That's incorrect but appears to be a bug in the switch's software but not something that's impact other brands of phones.
My ask here: Is there some setting on the Trio I'm missing to bypass the check performed by the Trio? Some sort of "always use advertised tagged VLAN" or "Ignore PVID in LLDP"? I can't statically configure the tagged VLAN on the Trio as it's not the same between buildings.
