I understand, and the ID's are different, the WAN is working. The primary issue is that these IP Phones have to have a specific gateway to function properly. The gateway must 172.16.10.150 in this instance, which works fine on the 172.16.10.x network, but won't work on the 172.17.1.x network. I guess I need a way to "bridge" my two networks, or get them on the same subnet somehow. It's a matter of poor design on the phone manufacturer's side. The phone boots up and identifies the gateway as it's phone switch. If I set the gateway of the WAN phone to 172.16.1.1, it wont update the phone switch... I have also tried adding both ip's (172.16.10.150, 172.17.1.1) as gateways for the phone, in both orders, and it got a little farther but failed... THANKS!
