7921G SIP Calls only

Is there a specific firmware to enable the port assignments for the SIP usage? Is there a way to configure the phone without using the call manager?

No, the 7921/7925 doesn't support SIP at this time. So must use SCCP, which requires CM.

Are the SIP Dual-tone options which are the advanced features of the 7921G the same for SIP calls?
