this could be issue with PT and DHCP. not sure if u can use router as dhcp and server at the same time.
then, in real gear, voice vlan in switchport command has more options; 4, I think. PT does not have that.
You could use dhcp pool on server for voice traffic.
Also, I would not use vlan 1, try different vlan id. that vlan is security risk and should be avoided all times.
you can find some samples that come with PT for voice and dhcp. check them out to see how dhcp is set up to be used by phones.
