GoldFax can automatically route received faxes to specific folders based on the called fax number, caller-id, etc. (DNIS, DID, TSID, CSID), or DID (Direct Inward Dial) numbers. DID numbers are very inexpensive virtual phone numbers (usually less than $1 per month) that route into a much smaller amount of real telephone lines.
All routing settings are done through the simple, easy to use Receive Routing tab in the GoldFax Manager interface.
