You do have a trouble with your configuration.
The XCAs signaling is not loop start,and you have tone supervision enabled (answer and disconnect).
Only one option could work,either you go loop start with answer and disconnect supervision, or you go with forward disconnect and no tone supervision.
When you enable both at the same time, only one type of supevision work.
Wich one depends on wich one was enabled first.
When you are on loops start, and have answer and disconnect supervision, It will bill you for the recording, since the quintum detects “voice” and thinks that someone is talking on the receiving end.
Good luck!!!!
