[Freeswitch-users] What is the recommended practice to use uuid_bridge?

Hi We have a FS which receives inbound calls (IB). Using FS's ESL we originate outbound calls (OB). We want to bridge the media of inbound to outbound calls. Should we be using uuid_bridge command with arguments IB and OB (uuid_bridge IB OB) or should we be using (uuid_bridge OB IB). Thanks Darshan
