T42G dhcp issue

Hi,
we have mixed environment with Polycom VVX and Yealink T42g phones.
Phones should receive DHCP address from voice vlan and tagging is configured on HP 5130 switches. CheckPoint firewall acts as default gateway between VLANS with allow all rule.
Problem is, that with LLDP enabled or DHCP Vlan option or even manualy vlan tag set yealink phones do not receive ip address. If i disable VLAN option completely phones succesfully receive ip address but from data vlan.
I would suspect switch configuration, but polycom phones do receive ip addresses from voice vlan without any configuration tweaking.
Can someone advise what should be checked?
