You have an IP route on the IP office that tells the system how to get across the VPN?

Also you should NOT have 2 DHCP servers setup even if one is the phone system only doing Avaya phones. Sure, that will stop computers from getting DHCP from the phone system, but it won't stop the phones getting DHCP from the Dtek instead of the phone system it would simply be first DHCP server to serve the address.
