Hello Zoltan, Thank you! I thought it was the UUID of the channel I had to pass to the SendMSG command. This makes things easier now!!

Its value will be relayed back in the "Application-UUID" header of the corresponding CHANNEL_EXECUTE and CHANNEL_EXECUTE_COMPLETE events.

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?
