Faxing with VoIP, broadband phone or internet phone often faces challenges that can be resolved with a few simple changes to your fax machine. This will allow most of the data to get to the receiving fax.. If your internet service is experiencing packet loss, jitter, or latency, faxing can be more difficult, or even impossible depending on the severity.If you suspect an ISP issue, fix that issue first before trying to send a successful fax.

If a fax machine looses data either with sending or receiving it will stop the transmission because it thinks that the other end has hung up. However, if you slow down the fax transmission speed, also known as Baud or Baud rate to 9600 , adjust the resolution to standard, and turn off ECM (Error Correction Mode), most of the data will arrive to the destination fax and allow for more successful faxing..
