Overview #
Direct Inward Dialing (DID) is a feature that allows businesses to assign unique phone numbers to employees or departments without requiring separate physical phone lines. Calls made to a DID number bypass a receptionist or switchboard, connecting directly to the intended recipient.
At Innovo Networks, we provide Hosted PBX solutions that include DID functionality, enabling businesses in South Africa to improve communication efficiency, operations, and customer experience.
What is a DID Number? #
A DID number, also known as a Direct Dial-In (DDI) number, is a virtual phone number assigned to an individual or department within a business. It is linked to a Hosted PBX system, allowing incoming calls to be routed directly to the relevant extension without requiring manual intervention.
- For businesses using Hosted PBX: DID numbers can be local numbers from anywhere in the world, assigned to team members regardless of their location.
- For businesses using traditional PBX: DID numbers are assigned based on the company’s geographical area.
DID eliminates the need for a central switchboard or IVR menu, ensuring faster and more efficient communication.
How Does Direct Inward Dialing Work? #
DID works by using your company’s Hosted PBX system, ensuring seamless call routing through the following steps:
- A customer dials a DID number.
- The call is routed through either:
- The Public Switched Telephone Network (PSTN) (for traditional systems).
- SIP trunks (for VoIP-based systems).
- The telephone provider forwards the call to the business’s Hosted PBX platform.
- The Hosted PBX system recognizes the DID number and directs the call to the corresponding extension, mobile device, or VoIP endpoint.
This automated process removes the need for an operator, allowing businesses to handle calls efficiently.
