[Asterisk-Users] Cisco 7960 Can't be unlocked

[John Mensel]

Odd problem here--I just got a couple of Cisco 7960s from Ebay that are not 
functioning as expected......

These 7960s can't seem to be unlocked for manual configuration via any 
mechanism that I can find.  If you go to settings, there is no option 9 
(unlock).  Available options stop at 4 (Status).  **# has no effect.  

The Phones report that thier current firmware version is 3.1 MF.G2. 

When plugged into a known good DHCP/TFTP server, the phones will *sometimes* 
get a DHCP lease that is reflected in Settings>>>Network Configuration, but 
at no point will they grab new firmware via TFTP.  DHCP server logs show the 
phones trying acquire a lease and then immediately requesting a new one.

If anyone has encountered a similar situation, please advise.

Thanks,

John Mensel
