[Freeswitch-users] Programatically constructing switch_r_sdp

Hello Team, Is there a way to programmatically copy the SDP from one leg to the other? I have a situation, where i have two incoming legs and want to bridge them without answering them in freeswitch. I want to know if i can copy the SDP from one leg to the other programmatically (Not via XML but via ESL inbound) I Found that there is a way to do it in XML dialplan like this: <action application="set"> <![CDATA[switch_r_sdp=(sdp here) ]]> </action> How to achieve something similar using ESL inbound?
