We have a UC520 connected to an 871 at a home site via vpn. About 18 months ago this configuration worked. Not sure what caused it to go down.
If the phone is brought to the office and plugged in it will come up fine. But over the vpn it will not work. Routing looks good. Have run some debug on the acl's and there is nothing being denied when the phone tries to come up. It is getting an ip address from the DHCP and getting the correct TFTP from the option 150 on the DHCP. I don't see a NAT issue either. Can someone please take a look at both configs and let me know if you see anything wrong?

the softkeys. You enable or disable them via TCL. Here is the long
