[Freeswitch-users] Reasons for uuid_bridge not appear not to work?

Got a slightly troublesome Lua script/dialplan combo that is not bridging calls properly. I am thinking that there must be some subtlety concerning when bridging of ACTIVE channels is not possible. The scenario is in an attended transfer where A calls B, B calls C, and then B ducks out. bridging A&C. As far as I can tell, A&C are NOT terminated, but something funny happens that prevents the bridge establishing a call path. Any ideas?!
