HP OfficeJet Pro 8710 fax not working when AT&T landline changed to AT&T digital phone (VoiP).

One of the pages that I looked at said something about a link below to set up the fax over (VoiP) but I did not find the link.

Any suggestions or ideas?

@carberryc, Welcome to the HP Support Community! I’m here to help.

I understand you are not able to fax on a VoIP line.

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 printer 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 printer to send a fax over a VoIP network.

If the VoIP provider offers a "Pass through" mode for the connection, that will offer better fax performance on VoIP. Also if the provider has "comfort noise" added to the line, fax performance can be enhanced if this feature is not enabled.

If faxing problems continue, contact the VoIP provider.
