[asterisk-dev] Hangup channel

[Rafael Seste]

Hi all!

I'm trying to solve some bugs on asterisk channel that I found on the
internet, it is the chan_usbb2k. It is a channel to work with a
usb-fxs adpater
I know that it is not part of asterisk but I need some help on how
asterisk handle channels.

This channel is not hanging  up when I on-hook the phone (fxs). The
channel stays busy for ever.

How can I hangup this channel when it on-hook the phone???
I know when it on-hooks I just need to know how to inform asterisk
that the channel hanged up.

thanks in advance
