What is the CSID?
CSID stands for Called Station ID. When someone sends a fax to your Faxxis number, the CSID is displayed on the sending machine’s display screen. You can configure your CSID to be your name, company name or a valid fax number in the Receive Settings area of the account administration website. Your default CSID is set as your Faxxis number.

People using WinFax to send outbound faxes may have problems sending to your Faxxis number if their CSID is all letters (a company name, for example). This is a bug in the WinFax software. If the WinFax user changes to a numeric CSID, this should solve the problem. The CSID is an identifier that is entered into the WinFax software by the user, usually a fax number, name or company name. The CSID is used to identify the WinFax user to other fax machines.
