Yes it is, if you tell kamailio to rewrite SDP by calling rtpengine
functions.

During your previous messages I never got the idea you were talking
about an uplink/provider interconnect (might be me just skimming your
mails). But without a config (of kamailio and rtpengine and a clear
network topology) it is not possible to tell what the problem is.

The standard config in the kamailio repo does NAT checks before calling
rtpengine, if you scrap those conditions it will trigger rtpengine on
all calls.
