Grandstream LLDP voice vlan issue

Unsure if anyone can help with this. I'm having an issue with grandstream phones and the PC port.
I have my network setup for LLDP, to automatically pass the voice VLAN to the phones upon boot-up (configured in router via DHCP). However, it appears that when I connect a computer to the PC-Port on the phone. The computer does not obtain an IP address. Almost as if the LAN & PC Port end up sharing the same voice VLAN. (Voice vlan is tagged).
If I reboot the phone, the computer gets an IP. but soon as the phone finishes booting and switches to the voice vlan, computer connected to PC port loses connectivity.
Phone works just fine though, It will boot-up and automatically switch to the Voice VLAN and have connectivity. But apparently locking out the PC Port (untagged data network)
Anyone have similar issue?
Switches: Cisco SG300's

Sounds like you phone is not putting the PC poet on VLAN 1
