[Freeswitch-users] Javascript: inconsistent session.ready() result when originating a call

[Marc Kellem]

I'm using Javascript to originate a new outbound call. The Session ready()
method returns inconsistent results when the call is answered. When it
returns false, the session's causecode value is 0. Am I doing something
wrong here, or could it be a bug?

A simple test script and log output is below. I'm executing the script from
the console using jsrun. I've noticed that switch_core_state_machine.c logs
a state change when ready() returns true. I'm not sure if this is
significant, but it might indicate a race condition.


---- test script ----

new_session = new Session(
"{ignore_early_media=true}sofia/internal/1000%192.168.1.10" );
if ( new_session.ready() ) {
 console_log( "info", "Call connected.\n" );
 // play audio....
}
else {
 // the causecode is 0 when this fails on a successful call attempt
 console_log("err", "Call not connected. Cause: " + new_session.cause + "["
+ new_session.causecode + "]\n" );
}


---- call connected log ----
