What you will see
Fax performance may be adversely affected by one of the following:
- Missed or dropped faxes due to ring detection issues with certain answering machines, or
- Missed faxes if fax connected to a DSL phone line via answering machine, or
- FOIP (fax over IP) could cause inconsistent results.
Download and upgrade the latest box firmware, and then perform one of the procedures below based on your symptoms.
This firmware improves device performance as follows:
- Increases the number of selectable rings on the AIO from 5 to 9 in an effort to prevent the AIO's fax modem from picking up a voice call, or the answering machine from picking up a fax.
- Improves the AIO's fax speed settings as VOIP (voice over IP) service providers typically recommend 9600 bps to 14.4 kbps for FOIP.
Reason: Digital-to-Analog conversion performed by a service provider's modem may cause signal loss, or a lower signal-to-noise ratio (SNR). The AIO requires an analog signal for fax functionality.
