I'm still not clear how to do this.

INVITE is usually processed by invoking route[RTPPROXY]. Now if i want to
forward it to another kamailio, what should i do?

Is the idea is like this :

INVITE--->kamailio1-----forward--->kamailio2--->route[RTPPROXY]--->Next Sip
endpoint

Client <----
route[RTPPROXY]<--------kamailio1<------forward-----kamailio2<---- reply
with SDP

If these scheme is correct, then i need to find how to do the "forward"
appropriately?
