[SR-Users] Re-Invite from callee With RTPEngine between RTP--SRTP

[me.projects at yahoo.com]

Hi, I have have Kamailio as SBC one-end is SRTP and other end is RTP
So I m using 
rtpengine_manage("replace-origin replace-session-connection DTLS=passive OSRTP-offer ICE=force SRTP")rtpengine_manage("replace-origin replace-session-connection DTLS=off SDES-off ICE=remove RTP")

1-Asterisk(RTP) -----2-Kamailio/RTPEngine ------ 3- Carrier with SRTP
I detect source IPs and to manage this all. 
When call is made from 1 to 3 all works and during call 3 send re-Invite to Hold Call .. We need to call rtpengine_manage and also when on 200OK reply of re-invite from 1.

How shall I detect that 1- if this is Re-Invite (has_totag() )and 2- its from Callee.
Please advise.
