[cisco-voip] 7940 to SIP - Manual or plug and play?

[Mac GroupStudy]

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?
