[asterisk-users] Understanding Asterisk

[John Signorello]

I assume you are going to with a VOIP provider.

Essentially, you have one DID and any number of channels/ports.

Typically, you pay per port with a minute charge.

Some people give you "unlimited" ports but charge a higher per minute fee.

In you case, where you currently have 3 lines, you would need 3 channels.
This would provide three concurrent calls to be in place.

Asterisk does not know anything about channels in this example.
If 3 calls come in it answers three calls.

If a 4th caller comes in , the VOIP prvovider will send the busy signal 
to the caller.
Asterisk does not see it.
