IP7961 phone not registering on clean built 2821 ISR CME server?

[rgordon-qsc]

I have a 2821 ISR router running CME 8.6, but I appear to be missing something in the configuration because the first test phone that I am attempting to connect to the system is hanging at "Registering".  It's getting a DHCP address from the server, but hangs after that.

Is there a debug command I should be looking at?

Do you have option 150 set on dhcp server for tftp server?

Have the ephone configured with right MAC address, telephony-system, etc?

This Document is a good starting point,

Try running these debugs and check

debug ephone detail

debug tftp events

debug ephone register

debug ephone error mac-address

Check the following options before doing

Option 150 (TFTP IP address ie CME IP address)

Telephony should

ip source-address

Also try manually registering this phone by setting manual ip address, Subnet, default router, TFTP Server and check if properly getting register.
