Direct Inward Dialling (DID) is a method of directing incoming calls to a particular phone number. Instead of being linked to a physical telephone line like a traditional phone number, a virtual phone number is assigned to a country, city, or region. DID numbers can be assigned to individual employees, departments, or groups, and are used to give a unique number to each employee’s extension, ensuring that calls are directed to the right person.
Using a DID number, hundreds or even thousands of incoming calls can be routed to the correct extensions simultaneously, which not only helps to expand your business capabilities but also provides excellent customer service.
A DID number serves multiple purposes. It can offer advantages and features to local telephone systems. By incorporating a foreign DID number into your company’s current phone system, you can expand your customer service globally. DID numbers can also provide access to non-PSTN services, such as VoIP, and offer local phone numbers to companies that deal with customers worldwide.
DID numbers allow calls to be routed to any network, including remote workers and satellite offices, enabling all individuals, groups, and locations to connect to a single private branch office? Additionally, a DID number with VoIP service allows you to redirect incoming calls to mobile devices, integrate with CRM, host conference or video meetings, and manage remote workers.
DID works in two ways, which are:
Public Switched Telephone Network (PSTN) lines
Voice over Internet Protocol (VoIP) direct dialing on the Public Switched Telephone Network
The PSTN system consists of interconnected trunks and a customer-hosted PBX telephone service provider. The provider assigns a block of telephone numbers to the customer as direct numbers.
When a caller dials a Direct Dial number, the call is routed through the trunk line to the customer’s PBX system. Once it reaches the PBX, the system identifies the dialed number and seamlessly connects the caller to the intended recipient.
With automatic routing, incoming calls are then directed straight to one of the company’s phone lines via the PBX, eliminating the need for an operator or automated maintenance.
The majority of companies today utilize VoIP technology. This type of phone system operates by enabling businesses to make and receive calls over the Internet without the need for physical phone lines or equipment installed in their office.
To incorporate DID with VoIP, companies can leverage DID numbers through Session Initiation Protocol or SIP trunks. Virtual links become accessible when a business requires “trunk connections” with SIP wiring.

One of the top priorities for any business is cost-effectiveness. The good news is that by utilize DID numbers, organization can reduce communication expenses associated with remote work and business continuity. DID numbers can be established in a central location and then distributed to remote employees. Furthermore, trunk cables are significantly less expensive for the company to purchase than traditional installations, and they are easy to install.
As additional equipment is not required, the direct option is one of the most practical solutions for growing companies. Adding DID numbers is also less costly than creating new phone lines for each new employee or office. Each department of a small business can have its own DID number. Additionally, the number of “extensions” available for DID numbers is unlimited.
DID numbers make it much easier to handle a high volume of calls simultaneously. With DID, customers can contact your business directly without waiting in line or navigating phone menus. Customers can directly connect with the person they need without navigating through prerecorded options. With a unique DID number, they can easily reconnect with the same representative, enhancing customer relationship management and ensuring faster, more personalized service.
DID numbers facilitate improved communication within an organization, as each employee receives a unique number that enables direct communication. This is particularly advantageous for remote workers, as they remain easily reachable through their extension. When integrated with VoIP and SIP trunks, DID numbers further enhance communication, ensuring seamless connectivity between team members.
For businesses offering 24/7 customer service with employees across different time zones, DID numbers are invaluable. They can be programmed to route calls based on the time of day, helping businesses extend their operational hours in targeted geographic regions.
DID numbers allow employees to seamlessly answer calls from their desk phone, laptop, or mobile device without interruption. They can route calls to any phone type, including VoIP, mobile, and landlines, making them ideal for call forwarding.
