2620 - 79xx Series VOIP Phones

I have some 79xx series VOIP phones that are acting VERY strange ... if you are familiar with these series phones once plug them into the PoE switch they look for a TFTP server with the call manager files to acquire all the info they need to work .... i have them set up on a 2620xm router running IOS c2600-ipvoicek9-mz.124-15.T14 along with call manger 4.3. My router is my TFTP server and i have hooked up and fixed over 50 of the same series phones with out a problem.

Now here is my issue ... when you goto press the SETTINGS button on the phone you are allowed to go into the settings of the phone to change all the ROUTER,TFTP,ETC info to allow you to connect your phone to the CALL MANAGER or you can set up DHCP and it will acquire the info automatically. When i press the SETTINGS button nothing happens .... i can reset the phone to factory defaults by holding the # button then 12345678*0# then 2 not saving the info and i can hit the restart buttons which is * 6 SETTINGS buttons together and that will let me restart the phone but i cannot manually set up this phone to do anything .. it will not acquire info form my DHCP server and will not find my TFTP server at all =( the phone SETTINGS BUTTON does not respond at all ..only when restarting the phone.
