What is Direct Inward Dialing (DID)?

We all know the pain of navigating clunky automated phone menus while a monotone robot voice drones on and on. How many times have you wondered if there was a way to skip all this frustration and just get through to the person you need?

Direct Inward Dialing (DID) is a telecommunications service that allows a user to directly dial a specific number within a company’s private branch exchange (PBX) system or private telephone network. DID allows incoming calls to be routed to any designated telephone that is connected to the business phone system, eliminating the need for a receptionist or automated phone menu. 

This type of service is beneficial for businesses, as it eliminates the need for a dedicated phone line for each telephone, allowing for increased flexibility and cost savings. Using Direct Inward Dialing also allows for simpler management of call routing, enhanced call security, and improved customer service.

Direct Inward Dialing: What Is It?

Direct Inward Dialing (DID) is a telephone service that allows businesses to assign each of their employees a unique telephone number. This allows customers to directly dial an employee’s number, instead of going through the main office line and waiting for a receptionist to connect them. Direct Inward Dialing allows for businesses to communicate with customers faster.

DID numbers are assigned by the phone service provider, and they can be local, national, or even international numbers. These numbers can be used to route calls to a specific employee, department or automated system.

Using DID services provide businesses with a number of advantages. These services make it easier for businesses to manage their phone system, as they can easily add or remove numbers when needed. An employee’s individual DID number can be used to keep track of calls and measure customer service.

How Does a Direct Inward Dialing Number Work?

Incoming calls are routed through the business's phone system to the individual's extension number. The user can then pick up the call directly without the need for an operator. This can be used to facilitate the flow of work through your business.

An example of how DID numbers can improve workflow is by assigning specific numbers to different departments or employees and assigning specific numbers to customer service calls. This allows businesses to quickly and efficiently route their incoming calls to the correct person or department. 

DID numbers are typically assigned in blocks of 10 or more, so that the caller does not have to remember the full number. Using DID numbers provide businesses with a cost effective way to forward calls through their business phone system. This allows businesses to keep their customers connected no matter where they are.

Direct Inward Dialing on PSTN

Direct Inward Dialing is a feature of the Public Switched Telephone Network (PSTN) that allows callers to dial a specific number to reach an individual extension without going through a switchboard operator. This feature enables businesses to assign DID numbers to their employees without having to invest in a PBX system or a direct line. 

In order to set up DID on a PSTN, you will first need to configure the DID number range on the PSTN. This will include allocating a series of numbers that will be used for incoming calls. The next step is to configure the business phone system to recognize and route the calls to the appropriate extensions using a business phone system.

Once the DID number range has been configured, each extension must be assigned its own DID number. This is done by programming the business phone system to recognize incoming calls and route them to the designated extension..

Finally, you will need to ensure that the correct personnel are notified when a call is received on a specific DID number by testing the number.

Direct Inward Dialing on VoIP

Direct Inward Dialing is a telephone service that can be used with Voice over IP (VoIP) technology. DID using VoIP is a cost-effective solution for businesses that need to maximize efficiency while providing quality customer service.

It's a phone number, a DID. A short number assigned to an extension is called an extension number. Some businesses will purchase a block of DIDs and utilize the last four digits to represent the various extension numbers. However, since there are fewer phone numbers available these days, it is less frequent and more challenging to do. Using a DID system over VoIP eliminates the need for a PBX system, which is an older technology. The new technology (VoIP) reduces on-site hardware and instead information is stored and programed in the cloud. 

By using DID with VoIP, businesses have the ability to quickly customize their phone system to match the ever-changing needs of their company. As new staff is hired or departments are created, the DID can be adjusted accordingly. This flexibility ensures that incoming calls are routed to the appropriate extension or department, which reduces the amount of time spent on the phone and increases customer satisfaction.

Another benefit of using DID over VoIP is the ability to create virtual conference rooms, allowing for multiple users to interact and work together.

Can You Send and Receive Faxes Over DID Numbers?

Faxing is a reliable and convenient way to send and receive documents, and with the use of a DID number, it is a secure and reliable way to do so.

When sending a fax over to a DID number, the sender needs to dial the recipient's DID fax number. Once the recipient's fax machine is connected, the sender can then send the document. The recipient will then receive the fax and can view it on their fax machine.

Receiving a fax over a DID number is just as easy. The recipient simply needs to make sure the fax machine is connected to the DID line and that it is turned on. When someone sends a fax to the DID number, the fax machine will automatically receive it.

DID numbers are particularly useful when it comes to faxing, as they can be used to increase security and reliability. By having a unique number for each user, it ensures that the faxes are only going to the intended recipient. It also ensures that the fax will not get buried in the shuffle of other employees’ faxes.

Save on Costs

With DID, incoming calls are routed through the telephone system without any operator intervention, thus allowing businesses to save on labor costs associated with having a receptionist. Using DID through VoIP could also significantly save when long distance calls are made. For example, if you have a business with multiple locations in different cities, you could use a single VoIP service with DID to connect all the locations. This would allow employees to call each other using the internal phone system, even if they are in different cities or countries. Because the calls are being routed over the internet, the long distance charges would be significantly lower compared to traditional phone networks.
