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);
• Outgoing: the channel has an output connection;
• Incoming: the channel has an input connection;
• Locked: the channel is blocked;
• Outgoing Lock: The channel is blocked for outgoing calls;
• Local Fail: The channel has a fault (at this point);
• Incoming Lock: the channel is blocked for incoming calls;
• Remote Lock: there is a remote lock (at the other end) in this channel.

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.

In the case of a GSM channel, the state is defined by one of the following values:

• Idle: the channel is free and available for calls;
• Call In Progress: the channel is busy on a call;
• SMS In Progress: the channel is busy sending / receiving SMS messages;
• Modem Error: an error occurred communicating with the modem channel;
• SIM Card Error: The SIM card is not present or is not inserted / detected correctly;
• Network Error: an error occurred while communicating with the network;
• Not Ready: The modem is initializing the channel.

And in the case of an FXO channel, the states are as follows:

• Disabled: the channel is disabled;
• Enabled: the channel is enabled.

Call state

Defines the logical state for each channel, which can be:

• Free: the channel is free;
• Incoming: the channel is receiving a call;
• Outgoing: the channel is making a call;
• Failure: the channel is in fault.

FreeSWITCH call states

Directly reflects the call state controlled by FreeSWITCH, which can be:

• new: Channel is newly created;
• init: Channel has been initialized;
• routing: Channel is looking for an extension to execute;
• execute: Channel is executing its dialplan;
• ex_media: Channel is exchanging media with another channel;
• cs_media: Channel is consuming all media;
• hangup: Channel is flagged for hangup and ready to end.
