Hi:

I am using mod_java. And in my script I was able to achieve using:


execute("sched_hangup", "+300 alloted_timeout");


However, when I try to run sched_api in the same way, system log returns that it's an invalid application. I have also tried to trigger it with many conditional channel variable api calls , but non of them seemed to execute the api command (because I turned on the highest level of debugging and see no where the sched_api is being called. 


The closest thing I got was by using "api_after_bridge" like the following, but it only launches when the bridge is teared down(which is not what I want). I originally thought after bridge means right after the 2 party is connected. All I want is to be able to play some message to leg A at certain time.


setVariable("api_after_bridge", "sched_api +10 none uuid_displace ${uuid} start /path/to/some.wav 20 mux");


I have been struggling with different combination for a week now.. Please shed some light if you know something. 


Thanks,

You need to pass the UUID to sched_hangup.


Usage: sched_hangup [+]<time> <uuid> [<cause>]

Diego:

You probably miss understood me. I said I was able to make "sched_hangup" work, but not the "sched_api" in the same way I script for "sched_hangup"


The problem was on the second paragraph. 


thanks,

sched_api is a fsapi command not a dialplan application, I believe sched_hangup is both.

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.

I can't seem to find the right thing to use in mod_java to execute api commands, only api_after_bridge

Judging by this error I would assume that you're still calling sched_api as a Dialplan application and not as an FS API command.


You need to figure out how to create an API obj in java and call sched_api from that object.

The syntax is different, but the api is the same as lua:

[anthony.minessale at g...]

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.

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 1256285888

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.

it's probably related to escaping the data.
I was sick of watching you suffer so i added api_on_answer variable to trunk.
