Default 9608's and DHCP

For awhile now, several months, I have been trying to tackle an issue with the 9608 series phone. I am having trouble getting the phone to receive a DHCP packet on the voice vlan. The phones will boot up, talk on the data vlan and then try to talk on the voice vlan. I have watched in wireshark and have seen them do DHCP discoveries on the voice vlan, receive an offer, and then they keeping doing discoveries. It is like they ignore or do not see the offers. On the VLANTEST DHCP setting, I can set that to 60 seconds and after time runs out, the phone will eventually figure it out somehow and then will start working. I just feel it should not get to that point though, should it?

Anyone else ever run into this?
