cant really do that, but what you can do is once they bridge is up, then

via API 

uuid_media off ${UUID}   this will reinvite FS out of the media path.

uuid_media ${UUID} will inturn take a call that is in bypass and reinvite FS into the media stream

Subject: [Freeswitch-users] XML dialplan for Bridging two incoming calls with bypass media

Hello Team,
I am new to freeswitch and trying figure out if there is a way to bridge two incoming calls using XML dialplan.

I saw that we can use conference app but i want to bridge them with bypass media at first and then involve freeswitch later if I require to play any greeting/announcements etc., 

caller ====> kamailio ====> FS <==== kamailio <==== callee   

Regards,
