How can I collect the end result of the test?

[aseques]

I am using a simple script that makes a call and plays and audio file. After the call is finished I try to collect the result, but I don't know where to get it.
I tried different approaches:

• Collecting the "OnReleased: reason: ??????????" (but there is a message for every step on the script)
• Collecting the last Handling PDU "1 REGISTER <401>"
• Reading the exit code (that generally it's just 0 unless the program crashes)
