Peter is using an Austel approved Courier DS etc wit the same SDL as mine.

Surely the S0 ring detection is when answering, not dialling out.

When I had my answer string set to three rings here in Binkley, the logs
showed ONLY the three rings incoming before it answered it (not 6 and not
1.5).  It took THREE Australian Ring-rings to answer the phone.
