[Freeswitch-users] Splitting a Call

Hello fellow FreeSWITCH users,
I'm using FreeSWITCH Version 1.0.trunk (16883) and I'm using the event
socket to break an in-progress call into two independently controlled legs.
I want to be able to work with each leg completely independently - hanging
up one without affecting the other. Per the docs:
http://wiki.freeswitch.org/wiki/Mod_commands#uuid_transfer I'm using
uuid_transfer with an inline lua script to work with one leg without hanging
up on the other. I'm setting "hangup_after_bridge" to false on both channels
and invoking uuid_transfer with the -bleg option but as soon as I transfer,
FreeSWITCH hangs up on one of the legs.
Here's what I'm sending on the event socket. (everything gets an "OK"
response from FreeSWITCH)
Set hangup_after_bridge:
api uuid_setvar 53d37581-1f90-44bf-860a-addbc8430e3a hangup_after_bridge
false
api uuid_setvar 9d1a4f2d-2ce6-40e5-ac84-62ad8c2d4654 hangup_after_bridge
false
And then do the uuid_transfer:
api uuid_transfer 53d37581-1f90-44bf-860a-addbc8430e3a -bleg
'lua:callee.lua' inline
api uuid_transfer 9d1a4f2d-2ce6-40e5-ac84-62ad8c2d4654 -bleg
'lua:caller.lua' inline
The callee leg (53d37581-1f90-44bf-860a-addbc8430e3a) is immediately hung up
and the caller leg runs fine. Here's the log messages: (6505551212 is the
caller and 5165551212 is the callee)

How can I get the callee leg to stay up? Is this not what -bleg is supposed
to do? Am I doing something wrong here? I've tried parking both legs and
invoking the lua on the channels but one of the channels still drops and the
uuid is no-longer available in the event socket.
Is there some other preferred way to split a call apart?
Thanks.
