[OpenSIPS-Users] double sdp.

Hi,

A and B are on the same proxy.

A calls B,
    (as I need transcoding I need to call rtpengine_offer here)
B returns 183 with SDP.
     (this implies calling rtpengine_answer in onreply_route)
 B lets the call time out
On the proxy I intercept the 480 returned by B
and I change the INVITE so that it point to SEMS
      (this ismplies calling rtpengine_offer again)

Issue: when you call 2x rtpengine_offer, you end up with a double sdp body.

So,
how can I instruct opensips to overwrite the body instead of appending one
?

wkr,
