[Asterisk-Users] How to shorten ringing stop detection on X101P clone?

[Goran Dj.]

When x101p clone receive ring signal from phone line, my voip phone
start ringing. But, if caller hang-up at some time, phone continues to
ringing 10 second more. How can I shorten that time?

Pause betwen incoming rings on my phone line is 4s, so when x101p clone
(wcfxo driver) do not receive next ring signal after 4.5 sec, call
should be consider as ended.

What should I change to set that time (4.5 sec) for incoming ring end
detection?
