Hi guys,
I've read anything on this argument on Wiki but I can't find a complete answer.
I need to bridge two calls in Lua, waiting the first to be answered. My basic script is:
local GwParams =
"origination_caller_id_number="..gateway..",sip_auth_username="..gateway..",sip_auth_password="..sip_passwd
local slegA =
"[ignore_early_media=false,"..GwParams.."]sofia/external/"..callee.."@"..sip_domain
local slegB =
"[ignore_early_media=true,"..GwParams.."]sofia/external/"..called.."@"..sip_domain
legA = freeswitch.Session(slegA); legB = freeswitch.Session(slegB); freeswitch.bridge(legA, legB);
It works but legA and legB are called at the same time. Using:
while (legA:answered()== false) do end;
between the two session do the job but called parties can't hear audio.
I promise to add a script on wiki if you help me ! :)
Thanks in advance.

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?

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. -MC On Tue, Sep 13, 2011 at 1:59 PM, Chrisbware <chrisbware@interfree.it> wrote:

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.

"'\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 ..

Just checked this script from cli: luarun test.lua -- local slegA="user/1000" local slegB="user/1001" legA = freeswitch.Session(slegA); if (legA:ready()) then legB = freeswitch.Session(slegB, legA); freeswitch.bridge(legA, legB); end Leg B is created after the leg A answered.
