I have a phone that was connected to ephone 1 and then I moved the MAC to a another ephone.  The old ephone worked fine.  then when I moved the mac address to another telephone # it won't boot up.  I am not able to get into the Network configuration.  I have done a factory reset on the phone, and it says that it is updating but it just won't boot up.  i have checked the Mac-address to verify that it is correct.  

Need a push in the right direction

Do you have this file on your tftp
it tells the phone which os to load, can be useful if it gets stuck
i copied this from cisco explaining how to convert from sip to sccp but the idea is the same
Run the executable file in order to install the SCCP software. Ensure that the new files are in your TFTP main folder.

Change the OS79XX.TXT file to reflect the new file name.

For example, if you download version 5.0(1.1), your BIN file is P00305000101.bin. Change the text in the OS79XX.TXT file to reflect this file name, without the .bin extension.

Reset each phone.

Q. Do you have this file on your tftp

A. No I don't have anything even close to that file name.  I am going through the link U sent, focusing on the boot up process.

Q. do you have the dchp 150 option set?

A. Sure do.  its set to the interface ID of the voip Vlan address.  option 150 ip xx..40.22.1

do you have
tftp-server server
tftp-server flash OS79XX.TXT
tftp-server flash:PXXXXXXXXXXX.bin
tftp-server flash:PXXXXXXXXXXX.loads

This set up the phone load process.
the os79xx.txt is only needed once. It might reload the firware every time the phone reloads....

Hey Greg,

I definitly don't have
tftp-server flash OS79XX.TXT

I am looking for some links that can help with getting that loaded.  I noticed that my problem with VOIP phones not being able to register happens on Switches that are not POE.  Also I work in an area that looses power a lot.  I am thinking that this has something to do with it.  I have tried to load the

Router(config-telephony)# load 7941 SCCP41.8-3-3S.loads   But nothing has changed with the phones

Thanks for the push in the right direction Greg

You create the OS79XX.TXT file yourself.
So as in the example you would put the below text into a bew word document
Then change the name to OS79XX.TXT and transfer the file to your router.
Then make sure it can be accessed by the phone
tftp-server flash OS79XX.TXT
Maybe the phones are loosing power and loosing their programming too.

TFTP: looking for term41.default.loads

I am still looking into the OS79XX.TXT FILE AS WELL

this is one of your Phone firmware files ... so download it and put in your TFTPboot folder

I never did need the OS79XX.TXT, but I don't have a CCO account so I just had to find the right files for my TFTP-Server.  

Here was the file that made the difference

tftp-server flash:dsp41.8-3-3ES2.sbn

Thanks for all your help
