Well, I'm an idiot. Forgot to remove the # in front of the modparam.

pv is populated with the SDP body now. Only strange thing is that $var(sdp) is 
set to 0 on on the second passing of below during branch routing after 
handling a 302 redirect:

rtpengine_manage("RTP trust-address replace-origin replace-session-connection 
ICE=remove");

xlog("rtpengine avp: $var(sdp)");

if($(var(sdp){s.len})>1 && has_body())
{
        $var(sdp)=$var(sdp)+"a=X-foo:bar\r\n";
        replace_body_atonce("^.+$", $var(sdp));
        $var(sdp[*])=$null;
}
