We have a couple 7970 phones that will not register with callmanager.  A
previous engineer told me that the there was a bug that caused the phone
to not register if they were not connected to callmanager for an
extended period.  We have had the phones offline now for years and I
just tried to plug them in and they will not register.  I tried to reset
the phone to factory based on the directions below:

Unplug the power cable from the phone and then plug it back in. The
phone begins its power up cycle. 
While the phone powers up, and before the Speaker button flashes on and
off, press #. Each line button flashes on and off in sequence. 
Press 123456789*0#. You can press a key twice in a row, but if you press
the keys out of sequence, the factory reset does not take place. Now the
lights should change color from amber to red.
Press 1 in order to maintain the current network configuration settings
for the phone when the phone resets.

Does anyone have any other suggestions to fix these?

Pete

Hi Pete,

That defect is only applicable if phones are powered up but lack IP
connectivity to CM for an extended period of time.  The workaround is to
power the phone down/up.

If that didn't do it you're in another state. Possibilities:
1. network issue - are the phones getting DHCP option 150 or DNS
resolution for CiscoCM1 to find their TFTP server?  Do the phones get
valid IP's, subnet mask, defeault gateway?  Can you ping the phones from
the CM server.  Is there any firewall or ACL that would block IP
connectivity?  On the CM server if your run 'netstat -an | findstr 2000'
do you see the IP of the phones in the output?  If not, your phones are
attempting to contact CM and the problem is closer to the phones.

2. dead phones - have these phones every registered successfully?  Are
they running SIP loads?  Do the icons and graphics on the LCD's look
differnt from any of your other phones?  Can you point your web brower to
the IP of the phone?  Are there any 'interesting' messages in the status
logs from the phone web page?

There are many components between 'phone' and 'cm' that may inhibit
registration.  We need a bit more info on what is working to figure out
what is not working.
