I agree here, SIP load should only be considered on newer phones not 7940/60s. Not enough memory on those older phones I understood.

By default it will be SCCP. You you either have to change the default auto register protocol to SIP and reset all phones or you could use a BAT function for SCCP to SIP. However, might I recommended you not change 7940 phones to SIP. A 7940 is considered a Type A phone (like a 7960 and I think a 7905 is in that group). Although they will support SIP you lose a lot of functionality when you do that. Dialing acts different (unless you build SIP dial rules) and many features are lost on these model phones. May I ask why you want to make them SIP phones?

If I want to migrate a 7940 from SCCP to SIP, do I have to manually go through the process or can I just plug in a 7940 into the network and when it talks to CallManager, if it's configured as a SIP phone, it will download the SIP firmware?
