Well, I didn't say you *couldn't* do it, just that it isn't the best option. For posterity's sake here is a sample of a Lua script that does basically what you want.
--
-- cc.lua
--
-- call control lua script - can it be done?
--
dialA = "sofia/gateway/fs1/9903"
dialB = "user/1001"
legA = freeswitch.Session(dialA)
dispoA = "None"
while(legA:ready() and dispoA ~= "ANSWER") do
dispoA = legA:getVariable("endpoint_disposition")
freeswitch.consoleLog("INFO","Leg A disposition is '" .. dispoA .. "'\n")
os.execute("sleep 1")
end -- legA while
if( not legA:ready() ) then
-- oops, lost leg A handle this case
freeswitch.consoleLog("NOTICE","It appears that " .. dialA .. " disconnected...\n")
else
legB = freeswitch.Session(dialB)
dispoB = "None"
while(legA:ready() and legB:ready() and dispoB ~= "ANSWER") do
if ( not legA:ready() ) then
-- oops, leg A hung up or got disconnected, handle this case
freeswitch.consoleLog("NOTICE","It appears that " .. dialA .. " disconnected...\n")
else
os.execute("sleep 1")
dispoB = legB:getVariable("endpoint_disposition")
freeswitch.consoleLog("NOTICE","Leg B disposition is '" .. dispoB .. "'\n")
end -- inner if legA ready
end -- legB while
if ( legA:ready() and legB:ready() ) then
freeswitch.bridge(legA,legB)
else
-- oops, one of the above legs hung up, handle this case
freeswitch.consoleLog("NOTICE","It appears that " .. dialA .. " or " .. dialB .. " disconnected...\n")
Thank you for your answer: I'll follow your advice.
Anyway, IMHO, Lua must be able to manage situations like this.
Languages strong integration is a plus
of FS that helps programmers to invent new services. Telling them
they still have to play with events
sounds a bit "old school". Again: it's only my opinon. Keep up the
good work!

Chris,
We're glad you like FS - we like it as well.
What you're trying to do is completely possible, but the way
you're trying to do it is probably not the best choice. Instead of
a local Lua script to control both calls, you are better off using
either one of two options: event socket entirely or event socket +
dialplan. It depends on the level of control that you need. If you
want ultimate control then just use ESL right from PHP (or
whichever scripting language you are comfortable with) and create
your call legs, watching for the requisite CHANNEL_XXX events.
(See http://wiki.freeswitch.org/wiki/Event_List
for a nice list.)
I suppose you could do it all in Lua but you'd have to keep
polling legA channel for the endpoint_disposition variable in a
while loop and then break out on various conditions. I'm not at
all a fan of that method. With the event socket you listen for
the events that are of interest to you and then act on them.
Very elegant.
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
:-)

How are you calling this Lua
script to begin with? What is the big picture, that
is, what is the problem you're solving? Some context
might help us give you a better answer.
Hi, thank you for your help, but doesn't
work. legA:ready() is true when the first
session start and not when the call is
answered. So legB is called at the same time. Any other suggestion? -----Messaggio originale----- Da: Sergey Scheglov <sid@eltc.ru> Inviato il: 13 Set 2011 - 17:15 A: freeswitch-users@lists.freeswitch.org

Try:
legA = freeswitch.Session(slegA);
if (legA:ready()) then
legB = freeswitch.Session(slegB, legA);
freeswitch.bridge(legA, legB);
end
