DTMF Routing: Dual-Tone Multi-Frequency (DTMF) requires the caller to enter an extension number when sending a fax. 

Line Routing allows you to assign a physical fax line to a user. 

CSID Routing: Call Subscriber ID (CSID) is based on the Fax ID which can be matched to a recipient. 

OCR Fax Routing: Optical Character Recognition (OCR) routes a fax to the correct user by recognizing the text on the fax through OCR, and finding keywords related to a recipient. 

DID: Direct Inward Dialing is a service feature that allows inward-directed calls to a PBX to reach a specific PBX extension without human intervention. 

ISDN: Integrated Services Digital Network is an all-digital network that allows the transmission of voice and data, though only one can be transmitted over a single line at any one given time.
