Easy Communication

In a typical PBX environment, a private numbering plan (or extension numbers) is used for communication within the office. Direct Inward Dial (DID)/Direct Outward Dial (DOD) numbers are logical PSTN numbers that can be ‘mapped’ onto a private numbering plan, allowing ‘internal’ users in an organization to directly receive or make a call; bypassing an auto-attendant or an operator.
