<DIV>Once a variable is set on a session (one leg) it presists till it's either "unset" or changed. Variables really don't have "default" values, there are just default ways that things work if the variables are not present. With that said you should only have to set variables like "hangup_after_bridge" and so on, only once on the A leg.</DIV>
<DIV> </DIV>
<DIV>The confusing part is what leg to set them on. The easiest way to figure that out, is to see how FS uses it. For example "hangup_after_bridge" is used by the Bridge application (actually in switch_ivr_bridge), so because it's an parameter that tells the bridge how to work, it needs to be set on the A leg. The bridge function connects two legs togetther, and the A leg is the one calling it.</DIV>
<DIV> </DIV>
<DIV>Other variables, the ones used for call origination, for example "origination_uuuid" are used to control how an outbound channel origiates the call. They could be used in the originate API call, with NO other leg preseent. If you are using them in a Bridge, then you must either set them on the B-Leg, or "export" them so that all new B-Legs created from the current, get those variables "cloned" to them. </DIV>
<DIV> </DIV>
<DIV>So in the case that you have more then one "Bridge" inside a condition, any variables you set with "set" will be there for each following bridge, however the ones you set in the channel of the bridge, the ones in the "[]" will not be there for the next ones. Becuase if the bridge fails, the B-Leg for that bridge is gone.</DIV>
