You can specify an "Event-UUID" header in your "SendMsg" command. Its value will be relayed back in the "Application-UUID" header of the corresponding CHANNEL_EXECUTE and CHANNEL_EXECUTE_COMPLETE events. On Wed, May 28, 2014 at 12:08 AM, Grant Bagdasarian <GB@cm.nl> wrote:
Hello,
Is there a state diagram available which shows the state transitioning for all Channel Events and Channel States?
Also, I’ve wrote a simple ESL application which listens for all events happening in FS during a single call, and I’ve been studying the Channel Events/States and the correlation between them. Very useful. I recommend every new ESL developer to do this.
I do have a small question.
When using the SendMSG method of ESLConnection to playback a file, the below sequence of events is generated.
Now my question is: is there a way to send some unique string with the sendmsg command and have that one appear in all the other events which are shown below.
I need to track the events which share a relationship. CHANNEL_EXECUTE and CHANNEL_EXECUTE_COMPLETE contain a unique Application-UUID, which is good and could suffice, but I haven’t found a way where I can relate the sendmsg command back to these two events.
I know there is the Unique-ID header, but I’d like every action to be uniquely identifiable.
Is that possible or am I asking way too much?
