Fax - Partially Received Faxes | RingCentral

« Go Back


SummaryYou might receive partial faxes, such as incomplete pages or pages are cut off. Faxing has known limitations when implemented as a Fax-over-IP service. These limitations are technology-based and industry-wide. Several VoIP companies, including RingCentral, use the T.38 standard for sending faxes over the Internet. Although the standard promises better reliability, that standard is still open to interpretation by various providers and cannot be maintained on an end-to-end basis. Follow the steps below to help RingCentral Support isolate where the issue is coming from.

Partially Received Faxes

• Check your Received Fax History via the Call Log section on your RingCentral Online account to determine if the partial faxes are being received from a single number only. See Filtering Call Log to learn how.

• If you have access to the sending machine (the machine from where you received the partial fax), lower the baud rate to 9600 and turn of Error Correction Mode and/or Overseas Mode.

NOTE: Steps may depend on the Fax Machine model.

• If the faxes are being forwarded to your RingCentral Fax Number from a different carrier, have the sender send a fax message directly to your RingCentral Fax Number. 

• If issue is happening on multiple sending numbers, gather samples that is from within the last 24 hours for possible carrier escalation. Please Contact RingCentral Support for assistance.
