Cloud phone DIDs (Direct Inward Dialing) are a revolutionary telecommunications technology designed to provide businesses with a reliable and cost-effective way of making and receiving phone calls. Through DID numbers, businesses can assign a unique phone number to each user. And, that particular number will help the employee to make and receive calls from any location in his/her business operations. 

Hence, this makes cloud-based DID an ideal solution for businesses that need to manage multiple incoming calls. Besides, it can provide employees with the ability to work from any location. In this essay, we will discuss the advantages of using VoIP DIDs for business, including cost savings, increased productivity, and improved customer service. 

Also, let us go through the different features they offer, and the ways in which they can be used. In the following paragraphs, let us evaluate how DIDs are beneficial for business and how they can be used to improve customer service.

Functions of DID with Cloud Phone Service:

It is clear that cloud telephony is the most cutting-edge and flexible way to use virtual direct-dial numbers. And, this became possible with the SIP trunking. On-demand, SIP makes the connections to the accessible trunk line. These in turn make virtual connections over the broadband and are utilized on need. Yet, remember that they are not real lines.

These virtual links are set up internally and connected by the software that binds all the numbers to your extensions. After that, your employees can access it on their own. If not, you can contact your cloud service provider to handle it.

However, in the past, it was different. Because setting all these used to take weeks. Furthermore, this whole setup was very costly due to its unavailability.

It is essential for you if you are a manager or a business leader, you must study this. By this, you can comprehend that while using business phone services. You can quickly become familiar with many features that require some time to master. Fortunately, most business phone service providers are able to provide expert onboarding and support. Therefore you can gain more than what the usual service providers do.

Uses for Direct Inward Dialing:

Suppose, you’ve already invested a certain amount of money in building your business structure. Did you validate its performance and whether it is truly the most effective method for handling incoming calls? Now, it is time to think about whether you might want a potential customer to immediately contact your sales department.

You might think about directing corporate customers in a different direction from those of small businesses. So, using DID can offer you the greatest benefits especially if you have separate lines for customer service and other departments. This will come true when a feature-rich business phone solution is used in your company.

However, there are some circumstances for you to consider where DID might not be the best choice for your company. On the other hand, limited employee availability may also influence the choice of DID. Also, it’s important to know that your company must decide how important it is for customers, vendors, and clients. Because, through this, they can contact departments directly.


Direct inward dialing works in a variety of ways, and businesses frequently modify the system to meet their particular requirements. Examples of common situations include.

Call Center Queues: 

DIDs play a very crucial role while handling calls in call centers. They route calls to the queues so that the next available agent can take them.

Call Forwarding:

These numbers are set up to move calls to any telephone number, including cell phones and IP phones. It comes to use especially when the employees are out of the office or for after-hours call coverage.


DID numbers can work with fax machines to send incoming faxes to the right fax machine.


Callers can leave messages for intended employees or departments through voicemail.


Customers or clients can call a particular extension number within an organization using DID. On the other hand, your employees can reach phone numbers outside the organization with direct outward dialing (DOD).

To consider, the difference between the two systems is that DID numbers can route incoming calls. And, DOD numbers route outgoing calls. Please keep in mind that both systems use unique phone numbers.

It is to know that DOD numbers are usually preferable for residential customers. But, DID numbers are typically used by businesses. Because the majority of businesses use Cloud PBX Systems to route calls internally without requiring direct dialing.

However, DOD is useful for certain companies to help employees use their desk phones to make calls without going for a PBX system.
