We are using an ASA 5505 running 8.2 with Sec Plus license. We're running into an issue where we created a second vlan for voice on the network and the phones cannot register properly to their hosted service on the outside. By default the phones are on vlan 1 and they work (in that they get an IP and NAT to the outside world and can register with our hosted service) but when we put them on a different vlan I get some odd results which appear to be NAT related.
We have the default vlan 1 and the second voice vlan 20 --- 192.168.100.x and 192.168.200.x respectively.
Ethernet0/0 = outside interface
Ethernet0/5 = trunked interface to our 3560 switch. Our 3560 is trunked on it's link to the ASA.
interface Ethernet0/5

interface Vlan20
nameif Voice
security-level 100
ip address 192.168.200.1 255.255.255.0
NAT config:
nat (inside) 1 0.0.0.0 0.0.0.0
nat (Voice) 1 0.0.0.0 0.0.0.0
global (outside) 1 interface
The 3560 has the two vlans (SVIs) created and trunked to the ASA. Routing is enabled on the 3560. Default gw for vlan 1 is 192.168.100.254 and for vlan 20 it's 192.168.200.254. Default route in the 3560 is the interface for the ASA = 192.168.100.1.
From the ASA I can ping the SVI interfaces and from the switch I can ping everything. When I put a device or a phone into vlan 20, I can ping that device from the switch and the ASA. But when I put a phone on vlan 20 and start to watch the traffic as it tries to go out and register, I get some "No valid adjacency" errors in the logs for the ASA and the phone never registers properly (which means no dial tone and no functionality.)

Public IPS have been changed to protect the innocent.
I've looked at everything I can find for that error message, but I can't figure out if this is a routing or NAT issue.
Any help would be appreciated.
