The usual way to send faxes using a fax machine with a handset

If your multifunction device or a fax machine has a handset, you can use this method to send a fax to a FaxExtension recipient.

The main fax number of FaxExtension recipients is +1 808-SEND-FAX (+1 808-736-3329). You should manually dial this number on your multifunction device or a fax machine with a handset to send a fax to a FaxExtension recipient. After the number is dialed and you are prompted for the extension, you should dial the recipient’s extension.

For example, if the recipient’s extension is 1234, dial +1 808-SEND-FAX (+1 808-736-3329) first. Once you are prompted for the extension, dial 1234. You will hear a fax tone now. Some devices will start sending the fax automatically at this point. Otherwise, use the appropriate command on your device to start sending the fax.

The convenient way to send multiple faxes

If your multifunction device, fax machine, online fax service, or a fax application on your computer allows faxes to be sent to a fax number with an extension, you can use this method to send a fax to a FaxExtension recipient.

The main fax number of FaxExtension recipients is +1 808-SEND-FAX (+1 808-736-3329). To send a fax to a recipient at FaxExtension, you must add pauses after the main number, followed by the recipient’s extension. We recommend adding between 3 to 5 seconds of pause after the main number.

For example, if your multifunction device, fax machine, online fax service, or a fax application on your computer uses a comma (,) to indicate a pause, and the recipient’s extension is 1234, then you should input the following value as the recipient’s number: +18087363329,,,1234. Some devices also allow using other characters to indicate pauses, such as pound (#) or star (*).
