The most frequent cause of a fax delivery problem is that the fax machine is out of paper or jammed.
The system attempts to deliver a message to the target extension until the Retry Limit is reached. If this limit is reached, the message is sent to the General Delivery Mailbox where it can be printed. Check the General Delivery Mailbox regularly or set up Message Notification for when the General Delivery Mailbox receives a new message. For how to set up Message Notification refer to the CallPilot Reference Guide.
If the fax machine is out of order for an extended period, reprogram the switch to redirect calls to an extension that has a working fax machine attached. Faxes that are waiting for delivery in the Fax Overflow mailbox are forwarded to the General Delivery mailbox, usually within several hours. Changing the Retry parameters on the Fax Overflow mailbox does not affect faxes that are already waiting for delivery.
