Use fax on a VoIP service
Fax memory
Voice over internet protocol (VoIP) services are often not compatible with fax machines unless the
provider explicitly states that it supports fax over IP services.
If the product experiences problems getting a fax to work on a VoIP network, verify that all cables and
settings are correct. Decreasing the fax-speed setting might allow the product to send a fax over a VoIP
network.
If faxing problems continue, contact the VoIP provider.
Fax memory is retained when there is a loss of power
Send a fax
The flash memory protects against data loss when a power failure occurs. Other fax devices store fax
pages in either normal RAM or short-term RAM. Normal RAM immediately loses data when power is
lost, while short-term RAM loses data about 60 minutes after a power failure occurs. Flash memory can
maintain its data for years without power applied.
