How Faxes Flow Through the System
2.1.1
Queues
There are four important queues in NET SatisFAXtion. Any fax that is processed
by the server is stored in one or more queues. The fax server’s queues should
stay relatively empty. If the queues grow in size over time, it can be an an indi-
cation that something misconfigured.
Scheduled Queue: This queue stores outbound faxes waiting to be sent. Faxes
that are converting, faxes that failed and are waiting to retry, and faxes that are
scheduled to send in the future will wait here.
Active Queue: This queue contains all faxes that are actively sending or receiv-
ing are stored here.
Outbox (Sent Queue): Delivery notifications are stored here before they are
delivered to the sender. Some clients (notably FAXability) will only collect noti-
fications when the user specifically checks. All other clients will retrieve notifi-
cations in real time, and nothing should be left here longer than a few seconds.
Inbox (Received Queue): Received faxes are stored here before they are deliv-
ered to the receiver. Unrouted faxes (delivered to Postmaster) will remain here
until manually routed. Some clients (notably FAXability) will not retrieve faxes
in real time since the client application is not running all the time.
2.1.2
Outbound Faxes
A fax is sent to the fax server from a client.
NET SatisFAXtion validates the phone number
The fax server places the call using a configured fax device.
When the fax completes, a status notification is sent back to the client.
2.1.3
Inbound Faxes
A call comes in from a configured fax device.
NET SatisFAXtion answers the call and begins receiving the fax.
Once the fax is completely received, the fax server makes a decision where to
send it.
The fax is delivered it to the client.
