The short answer
Fax can still work, but the way it travels is changing. As the traditional copper network is gradually replaced by IP lines, some old machines connect less reliably.
Sending from Faxturbo is designed for these IP networks. The how it works page explains how a fax crosses them.
What is changing
Operators are progressively moving subscribers from the copper telephone network to voice over IP, France included. The fax signal, designed for analogue lines, must now be carried over a network that compresses voice.
The outcome is uneven. Many faxes pass without trouble, while others fail or lose quality, particularly on older machines or very long documents.
What it means for you
If a transmission fails on a recipient who used to receive faxes without issue, a line migration may be the reason. Ask them to check how their line is connected.
Keeping documents short, using clear black-and-white pages and trying again at another time often helps. Where possible, offer the recipient an alternative such as email, or read about receiving faxes on a modern setup.
Key points
- Telephone lines are moving from copper to IP
- Fax can lose reliability on migrated lines
- Failures on a formerly working number may relate to the migration
- Short, clean documents transmit better
