We want to implement the following topology :
INVITE--->kamailio1-----forward--->kamailio2--->route[NATMANAGE]--->Next
Sip endpoint
Client <----
route[NATMANAGE]<--------kamailio1<------forward-----kamailio2<---- reply
with SDP
So the caller to callee will be processed by one kamailio and callee to
caller will be processed by another kamailio. Both kamailio will be up with
a public IP. How this can be achieved?
