Fax Troubleshooting Checklist


Limitations of Fax over VoIP

For sending an occasional fax, many business customers find Fax-over-Internet services to be cost-effective and adequate for their needs. However, faxing over the internet has known limitations. RingCentral uses the T.38 standard for faxing and adheres to the FCC guidelines regarding its use. This standard is interpreted differently by the various carriers and service providers on the public telephone and internet networks. Given this, the T.38 standard cannot be guaranteed on all end to end connections. As with any new service, it is best to test speed, quality, and reliability in advance of adoption.
If your business is heavily dependent on regularly faxing large, multi-page documents, we recommend that you maintain an analog landline and a traditional fax machine for reliable and consistent performance.

Listed below are basic troubleshooting steps for common topics and fax failures that you may encounter. If you are unable to find resolution to the issues listed below, please Contact RingCentral Support for assistance.
