Description
This knowledge base article explains the difference between Single Number Reach and Call Forwarding on the ISU phone system. Both features allow calls to your ISU desk phone to be answered from another location, but they differ in how calls are handled, where voicemail is stored, and which phone number appears on the caller ID.
