Thanks to c6burns on IRC channel for the tip to use execute_on_answer in combination with eval, and of course everyone here that pointing me to the right direction.I was able to execute sched_api with eval, but not with the combination of execute_on_answer. The argument just don't get parsed as the eval argument. Here is the code:setVariable("execute_on_answer", "eval sched_api(+%ld none uuid_displace <some uuid> start /usr/local/freeswitch/sounds/en/us/callie/misc/8000/final.wav 20 mux)");Here is the log:2009-10-23 16:17:53.633189 [DEBUG] switch_scheduler.c:214 Added task 2 sched_api_function (none) to run at 1256285888EXECUTE sofia/internal/1688004@192.168.1.66 eval(+OK Added: 2)2009-10-23 16:18:04.52701 [DEBUG] switch_channel.c:1927 sofia/internal/1688004@192.168.1.66 execute on answer: eval(sched_api(+37 none uuid_displace 84d74f41-8668-4138-943f-f076e94046ad start /usr/local/freeswitch/sounds/en/us/callie/misc/8000/final.wav 20 mux))EXECUTE sofia/internal/1688004@192.168.1.66 eval(sched_api(+37 none uuid_displace 84d74f41-8668-4138-943f-f076e94046ad start /usr/local/freeswitch/sounds/en/us/callie/misc/8000/final.wav 20 mux))The first part of the log is when I just do execute("eval", "${sched_api(+%ld none uuid_displace <some uuid> start /usr/local/freeswitch/sounds/en/us/callie/misc/8000/final.wav 20 mux)}"); And I simple get a OK, and then later on the sched_api gets executed.However, on the excerpt of the second log. which I use the combination with execute_on_answer like specified in the yellow hight code above. It doesn't simply return a OK, instead it shows the whole blob of code. and does nothing later.On Thu, Oct 22, 2009 at 4:09 AM, Anthony Minessale <anthony.minessale@gmail.com> wrote:
Yes you need an API object as described in other email.
Which line of code from java caused that segfault
It looks like a simple NULL string issue that we may want to hunt down.Anthony Minessale IIOn Wed, Oct 21, 2009 at 4:44 AM, Henry Huang <red.rain.seven@gmail.com> wrote:

So how would you trigger it from a script dialplan? The only time it seemed to work is when I did setVariable("api_after_bridge", "sched_api blah blah blah");
but then it gets executed after the channel's been teared down. I thought api_after_bridge means right after the call gets connected.
I need something to execute an api command right before or right after the call gets bridged.api_after_bridge is a channel variable, so using setVariable works just fine. If you need to sched_api is an API only. Check these out:
http://wiki.freeswitch.org/wiki/Mod_commands#Misc._Commands
So you need an API object in order to use it. I don't know the syntax for creating an api obj in Java but in Lua it goes like this:
api = freeswitch.API();
res = api:execute("sched_api","+300 none my_api my_api_args")
Remember, if the method you are using isn't found in the dial plan tools then it isn't a dial plan application. Make sure it's on the list:
http://wiki.freeswitch.org/wiki/Mod_dptools
On the other hand, API commands are listed here:dptools require a session object, api commands require an api object...
