Does Auto-VoIP somehow allow multiple untagged VLANs?

I have the VLANs set to UNTAGGED for both the data (vlan 1) and the voice (vlan 4088). If I try to tag the voice traffic, the phones stop working.
Why do you wonder? You can't -never- assign untagged ingress frames a switch into two different VLANs. Never. Mess is predictable. What will happen is you cause what is known as asymmetrical VLANs - something not supported here anyway. To be correct: It's the PVID defined on the port defining the one and only VLAN these frames will be assigned to.
