Understanding Fax Delivery Retry Settings
When the system calls a fax machine that is busy or unavailable, the system tries to deliver the fax again as soon as
another fax port is available. When the specified number of delivery failures occurs, the system waits the number of
minutes specified to start another set of delivery attempts.
For example, on the Fax Setup page the Attempts per set = 2, Number of sets = 3, and Delay between sets = 3
minutes, the system dials the delivery number two times, each re-dial occurring as soon as a fax port is available. If the
system receives a busy signal with each attempt; it pauses for 3 minutes before attempting a second set of delivery
attempts. If the second set fails, the system stops trying to deliver the fax and sends an error message to the
subscriber fax box.
The default retry settings are adequate to control how many times, and how often, the system tries to send a fax.
Consider the following before changing the default retry settings:
• Busy fax ports might cause a longer delay between sets of delivery attempts because the system must wait for a
fax port to become available. The delay between sets of attempts is never less than the value specified.
• Problems with the delivery retry settings can occur when the system has more than one fax port because the
maximum number of pages in a single delivery is configurable.
For example, if Max pages per delivery is set to five, then any fax containing more than five pages is sent as two
separate faxes. The first delivery is queued to the first available port. If the second fax port is available, the
remaining pages are queued to the second port.
If the first fax port successfully connects to the delivery number, the second fax port receives a busy signal because
the fax machine is receiving the first five pages of the fax. If the
Attempts per set and Delay between sets fields
are set too low, the second fax delivery times out and is never delivered.
