[Freeswitch-users] Need use static variable every time execute DialPlan

Hi, Iam having this situation: The leg A calls freeswitch and I execute a script in Lua and make an originate to leg B. I execute an outbound socket and listen a socket which my $uuidLegB = $info->getHeader("unique-id"); is legB uuid and inside this outbound scrip I detect tone and transfer into DialPlan. The problem is that I want to bridge leg A with B, but Iam trying to use uuid_bridge but I lose uuid Leg A, how can I get the uuid Leg A inside script outbound or how I can set an static variable inside DialPlan which can I put this uuid of Leg A. Because I test creating a variable inline or some tricks and every time DialPlan executes forget everything Thanks
