7960 switch from sccp to SIP firmware without CCM?

Can you switch firwares of 79xx phones without ccm? For instance, I have some 7940 on CCM and some I want to move to an open source platform. If I did not have CCM, could I upgrade the firmware with just a tftp server and the files?

Re: 7960 switch from sccp to SIP firmware without CCM?

no, you cannot change the load of a 79xx phone without having call manager provide the load to be used, via tftp configuration.

yes, tftp is used to get the new load but CCM must tell the phone to use it through CCM configuration.

please see the following link for more info on the 79xx sccp to sip and reverse process:
