FAX over VOIP

 



Fax Machine Settings

  • Set the baud rate to 9600 or below: Menu options might refer to setting as "transmission speed", "compatibility mode", or "VoIP mode". Slower speeds can help ensure more data gets to its destination. Higher speeds increase the chance of failure from packet loss, jitter, and/or latency. The more pages in the fax, the more impactful this setting can help increase reliability.

  • Disable Error Correction Mode (ECM): ECM tells the machine to retransmit when noise, poor signal strength or packet loss is detected. But packet loss, jitter, and latency exist on the Internet normally, so the retransmits increase call duration, increasing instability of the fax signal. Disabling ECM prevents this retransmit signal.

  • Set fax resolution to "normal": Using normal quality instead of high, fine, or ultra-fine can help increase fax speed and reliability. This reduces the amount of information (packets) that need to be transmitted.

  • Disable dial tone detection: Note: Only change this setting if the fax machine fails to dial outbound properly.
