Simple Cisco 1861 Router with CME Configuration
I have set up CME numerous times on 2800 and 3800 series routers but I cannot for the life of me get it working properly on a new 1861 router (with internal switch). I've set up separate voice and data VLANs, DHCP and CME. The IP phone gets an IP address but then returns TFTP timeout when trying to download the firmware. I cannot ping the single router interface (FastEthernet0/0) which I believe should be the TFTP server IP as well.
I did not assign IP addresses to the FastEthernet0/0 sub-interfaces because I got an "overlaps with Vlan X" error as well. I would like to have the sub-interface IP on the same subnet as the Vlan if possible. Although I'm not exactly sure what I need that address for.
The problem seems to be that the "switch" within the router is not communicating with the router. In the past I've set up trunks appropriately between the router and a standalone switch but I'm not sure what to do here. Please look at my configuration and tell me what the problem might be.

I'm trying to use the switchports on the router. I think that's where I got confused, i was somehow trying to trunk the switchports to the router as though they it was an external switch.
I removed the subinterfaces as you suggested and I've added a loopback interface of 172.168.0.1 and set the dhcp option 150 to that address and it's working now. I always wondered what loopbacks were useful for on routers, now I know - thanks!
I couldn't set the loopback IP as part of a VLAN, VLAN #1 in this case. What's the point of having VLAN 1 if I cannot put router addresses on it?
Next step is to add more phones, then another 1861 router with CME and trunk them using H.323.
I will accept your above solution lrmoore. Here's my configuration as of now. Please let me know if there's anything I could clean up or that is not to convention regarding VLAN IP addresses and such.
