HP 6110xi cannot send faxes using VOIP Telephones

We are always testing new technologies, so we found the latest issues when using a fax w/ a VoIP line service (i.e. Vonage, Voicepulse, Packet8, etc.). Most fax machines and/or fax modems have trouble sending/receiving on these types of lines. You will find that most hardware vendors (HP, Brother, Canon) will suggest to lower the baud rate to 9600 and turn off error-correction-modem (ECM). We tested an HP 6110xi All-in-one (fax, copier, scanner, printer) and had to rely on HP tech support to get us into the system programming. Remember, this is for a specific HP model, so, try this at your own risk for other models:

1. Press * and # at the same time, and then release both keys
2. Press 1, 2, and then 3, releasing each key before pressing the next
3. The display window should read "Service" with a revision number
4. Press the right arrow button once
5. The display should read "System Configuration"
6. Press Enter
7. Press the right arrow button until "r/w parameter" appears in the display
8. Press Enter
9. The display should read "parameter 0"
10. Press 153
11. Press Enter
12. The current value will display
13. Press 2, then press Enter
14. Press 159
15. Press Enter
16. The current value will display
17. Press 2, then press Enter
18. When modifications are complete, press Cancel repeatedly until the date and time appear in the display

We were able to successfully fax after making these changes. We also turned off ECM (error correction mode) to ensure the highest success rate.

Let us know if this does/doesn’t work for you!
