I have some questions about busydetect parameter and the tutorial 11.2. Resolving hangup detection problems with fxo cards

Q1. Does busy detect works when the port signalling is fxs_ks?

Q2. How I can check inside asterisk if the busydetect is really configured? I configured it in the /etc/asterisk/zapata.conf and I restarted asterisk. The busy tone is generated with the proper cadence but asterisk is not detecting the busy and does not release the line.

Q3. In 11.2. Resolving hangup detection problems with fxo cards it is reported the following sentece:
By default, asterisk listens for a busy tone or a a dial tone on the line to detect if the line got hung up.
Even at the end of the call the busy line is generated, asterisk does not detect it and does not release the line. This sentence get me in confusion. I've understood that, if busydect is enabled asterisk detect a busy cadence whithout really check the prequence. Is this correct?

Q4. How I can troubleshoot this issue?

Thank you very much for your help
