You are absolutely right. I am experiencing the *Problem 1*. I never
experienced your *Problem 2*.
In my opinion my problem is related to the call supervision (reverse
polarity or voltage drop) being missed by Asterisk on occasion. I do
not use busydetect as I do not want to have false positives.
Good luck with your Problem 2 struggle.
