[Freeswitch-users] Re4: Lua "two steps" bridging

[Chrisbware]

Hi Michael,

a PHP script connect to Event socket and launch "luarun  call.lua <legA
number> <legB number> <sip account number>

Script call.lua, upload sip account password from a DB and then call A
number and B number using the same SIP account, bridging them.
What I'd like to do is:

- place call to legB number only after legA has answered the call
- detect hangupCause on both legs to check if something goes wrong
- return SUCCESS or hangup cause to the PHP script

Is it science fiction? With Asterisk isn't so hard to do and, since I'm
in love with FS, please don't disappoint me :-)

Chris B.
