Hi, I am working on encrypting SDP crypto parameters when using SDES (developing csipsimple). I am trying to write a module which will handle invite just before it gone, but have a strange problem... When I set priority in my module on Transport_level (or higher ex. >= 8) then I cannot access sdp (multipart->body->data), it is created, but it's empty... But when I less priority of mod-msg-print (for example on value = 7), then I am able to handle SDP in my module callback as expected. I noticed that it happen when my module has priority lower then 8 (transport). If I do not change priority of mod-msg-print, my sdp modifications come about after message is sent...
