[cisco-voip] 7905G phone does not boot up

[Matthias Schaerer]

Francisco,

You say that the phone is new, but from your description it looks to me 
like the phone has 
already some certificates loaded (CTL). Can you look up Settings>Security 
Settings and 
see if there is some Hex lines displaying under CTL? If this is the case 
then you have
to erase all config on the phone and it should boot up again.

>From what I've seen the phones (in my case it was a 7940) stop the boot 
sequence after 
having a mismatch between a previously used TFTP server that must be 
hidden somewhere
in the CTL string and the new DHCP advertisement of a different TFTP 
server. The phone 
keeps looping in DHCP.

I've had this happen before on some 7905's that are attached to ports
at 100Full. Setting the ports to 100half or back to auto has fixed it
for me.
