you are better of putting a sip proxy in front and using that to modify messages in that manner. On Wed, Jan 6, 2016 at 12:33 PM, John Nash <john.nash778@gmail.com> wrote:

I am trying to experiment few things that required me to change SDP (Using media bypass mode).

I am able to change switch_r_sdp from a /perl/lua script successfully for Invite message using ... $session->execute("set","switch_r_sdp=$$resp{sdp}");

but I also want to change SDP of 183 session progress message I tried executing same code in scripts fired on 183 message but it doesnt seem to be changing SDP

Is that even possible?
