3524PWR Issues

I received my 3524PRW switch today and it has been busting my brain.
I needed to remove my HWICD-9ESW from my 2811 router because I needed more powered ports!
I am running a router on a stick w/ vlans 1, 101, and 107 (101 is Data valn, 107 is Voice vlan, 1 is management) on f0/1 of the router. Router is set up with OSPF. Router IOS = 12.4(15)T1, Switch IOS = 12.0(5)WC17.
PCs connected to the 7960s are able to communicate and get DHCP addresses with no issues. 7960s do not get DHCP configurations!
The only thing that has changed is I removed the 9ESW-PWR interface and the vlans 101 and 107 where I had the same IP address assigned to the VLANs as i now have assigned to the f0/1.101 and fo/1.107 interfaces on the router.
The 2811s sh ver is:

When I look at the mac-address-table on the 3524PWR, I can see that the phones are connected to vlans 101 and 107 and if I open CNA, they show in the topology.
I am able to ping all interfaces on the router and the switch's VLAN1 IP Address from any device on my network.
What am I missing????

Comments
The phones were connected to f0/1. 6,7, and 8. Configs are duplicated on 6-8 as show for f0/1 in OP.
I suspect it has something to do with the router config now. I decided to go back to my original config with the 9ESW installed and loaded what i thought was the previous config and I now get the same results with the phones pluged into the 9ESW (f0/1/0-3)
I know it is something simple I am missing, but have been away from the studies too long.

You got the 3524pwr and configured it identically on the interfaces that you had on the 9ESW module, and the PC attached to the phone can get DHCP and connectivity, but the phone can not.
If what I stated is true, I think I know the answer:
I had the same problem a few months back, I even posted a blog post on it: Cisco Treks: 3524 Phone Connectivity
I'll summary is so you don't need to read it:
You need to configure the following on the 3524:
Where 10 is your data vlan, and 20 is your voice vlan.
This is the old school way of configuring Voice VLANs. I learned it from some people on these forums, hopefully it helped you.
Not sure where I FooBARed the 2811 config, but as I suspected, that is where the problem was. The good (or bad) thing about keeping copies of all the configs I have done in the past is as some point I will find a previous one that works. As I mentioned before. I re-installed the 9ESW module and tried to go back to the original config ... but I had one that did not function properly. I eventually located an earlier version that worked and the phones registered, finally while plugged into the 9ESW. I moved the phones over to the 3524PWR one at a time and they registered right away without issues.
From there, I changed the voice VLAN IP Address to no IP address and created a sub-interface on F0/1 for VLAN 107 (Voice VLAN), setting the ip address to the prior VLAN101 IP Address and set up nat.
Everything came up again
Then I did the same thing for the Data VLAN 101.
Everything came up again!!!!!
Saved the config to start, powered off the 2811, removed the 9ESW and powered on.
Victory ... of course, the normal errors associated with a config file that does not see a module it was expecting!
Morale of the story ... keep track of the most recent configs that work!!!!
