Channel state

Reflect the state of the channel on the board. In the case of E1 links, the state may have one or more of the following:

• Free: the channel is free;
• Busy: the channel is not free (or occupied, or failure);

In the case of a FXS channel, the state is defined by one of these values:

• On Hook: the phone connected to this channel is on-hook or disconnected;
• Off Hook: the phone connected to this channel is off the hook;
• Ringing: the channel is being called;
• Failure: the channel is in failure due to communication problems between the central and the plate.

Call state

• Free: the channel is free;
• Incoming: the channel is receiving a call;
