Hi Support:
Many widely used SIP/RTP stacks such as Radvision SIP Toolkit and well-known open source stuffs often provide an interesting feature of hooking SIP/RTP message which in general is used for unique manipulation of SIP/RTP packets e.g. encryption or decryption or transforming etc.
Over research of media engine, I guess author of median engine also gives us such kind of gift.

I: when Hooking of SIP packet, upon event SipModifySipMessage by ModifySipMessage API Proc;
II: when hooking of RTP packets, upon EnableRawRtpPacketAccess API proc;
++++++++++++++++++++++++++++++++++++++++++++++++++++++++
My guess is right?
