    I would like to have all SIP solution, using sip based ip phones and sip
    based voice gateways, which sw I would need.
    If I would use CCM for registering sip phones, do I still need to use Cisco
    SIP proxy ?
    Which is the difference in functionality between these two ? Is Cisco SIP
    proxy SIP based IP PBX ? (as CCM).
    Can I define voice gateway as SIP based in CCM (I have seen only MGCP/H.323)
    Hope someone can clear this SIP questions to me,

    I think you need CCM 4.1 for SIP trunking support.
