In addition to lowering the modem speed, keep in mind there are many environmental parameters that can also affect faxing over VoIP. Try the following:
- Verify no other applications or computers are downloading files. While VoIP operates separately from the computer and they do not normally interfere with each other, the amount of data that can be transmitted from all devices on the system at one time is limited. If a fax is being sent or received and a computer begins downloading, it will consume bandwidth and could prevent the fax from going through.
- Resend the fax at an "off-peak" time. VoIP is an Internet application, so it is susceptible to network congestion. If you have ever noticed a website that usually loads quickly taking a long time to load, then you have experienced network congestion. Because faxing is a time-sensitive process, network congestion on your VoIP system may cause fax transmissions to time out before your machine can fully send them. You may be able to avoid this by sending the fax later.
- Contact your VoIP provider and ask if they can optimize the network settings for fax transmission.
