What is a DDI number?
DDI, an acronym for Direct Dial-In, also known as Direct Inward Dialing, is a cloud telephony service that allows callers to reach specific extensions to a specific department within a business directly without having to go through a receptionist, an automated menu system, or an IVR.
To put it simply, DDI numbers are like personalized virtual numbers that look just like any other number and allow the callers to get in touch with a specific team and go directly to that location or an extension of a company. DDI numbers come in a variety of forms and serve different purposes as per their configuration.
What are Direct-Dial-In numbers used for?
DDI/DID numbers can be used in a variety of ways, depending on the role they need to carry out. Here are some examples of how Direct-Dial-In numbers are used:
- Provide Individual Access: The most typical use of DID numbers is to empower the callers to bypass the main switchboard and connect directly to the person or team they need.
- Provide Personalized Service: DID numbers are also used to offer personalized service to important clients by establishing direct contact with a particular person or department within a business.
- Efficient Communication: Most organizations employ DDI numbers to streamline the telecommunication process and minimize the time spent by the callers navigating through a phone system.
- Improve Productivity: These numbers also help employees spend less time answering and transferring calls to the intended person/team to achieve higher productivity.
What is the difference between a DDI number and a DID Number?
When referring to DDI and DID numbers, there’s actually no difference between the two; these are just two different names for the same tech and are often used synonymously. The only difference is that the term ‘DID’ is primarily used in Europe and Oceania, and ‘DDI’ is more widely used in the USA and other countries outside of Europe.
How do DDI numbers work?
We know the workings of a typical business phone system, where you make a call requesting help to the business’s phone number, the receptionist picks up the call, and then manually redirects it to the concerned department.
DDI numbers eliminate all this hassle and work directly by connecting to the person or team you want to contact. And to make use of it, a business needs first to purchase a range of DDI numbers from a provider and assign each to a specific extension or phone line that leads to an appropriate department.
To give a better understanding of the system’s working, here’s a breakdown:
Step 1: A caller makes a call to a DDI number of a business.
Step 2: The call is then routed via the Internet to the correct phone number of the business.
Step 3: After that, it is connected to the business’s phone system.
Step 4: Now, the PBX identifies the DDI number.
Step 5: Then, the PBX automatically re-directs the call to the appropriate person/team/department.
Step 6: Finally, the extension phone rings and the concerned personnel can answer the call.
Now that you’ve learned how DDI numbers work, it’s time to learn where to obtain one. Well, the next topic is solely about that.
How to get a Direct Dial In (DDI) number?
When considering acquiring a Direct Dial-In number, there’s no answer other than obtaining one through a cloud-based phone service provider. To make the process even simpler for you, here’s a step-by-step description of how to do so:
- The first step is to choose a VoIP provider, such as KrispCall, that offers DDI numbers.
- You will now have to create an account on the website of the provider you have selected. As part of this process, you may have to provide information about your business as well as your contact information.
- Once you have an account, in the next stage, log in to the provider’s dashboard or portal to select a DDI number of your choice.
- In the next step, you can begin configuring your phone system in accordance with your needs.
- Finally, test your cloud-based phone system’s DDI number by making a test call.
7 Benefits of DDI/DID Numbers For Your Business
If you are a business owner, implementing a DID number can bring loads of benefits that can significantly boost your business’s telecommunication. While there are a huge number of advantages, here will discuss seven most significant ones:
- Improved Customer Service: As DID numbers simply eliminate the need for call queues and waiting time and enable customers to directly connect with the relevant person/team, their existence itself results in improved customer service.
- Stronger Professional Image: With DDI numbers, each department can get its own dedicated phone number, and thus, clients can easily reach the specific person they need, enhancing the overall professionalism of an organization.
- More Cost Savings: It might sound ironic, but these numbers can help businesses save money by enabling faster communication between employees, customers, and team members.
- Increased Efficiency & Productivity: DDI/DID numbers help improve efficiency as well as the productivity of the employees as all calls go directly to the intended recipient, eliminating the need for manual transfer or going through an operator.
- Better Marketing & Branding: You can obtain special DID numbers in the form of vanity numbers for targeted marketing campaigns. Use those to gauge the effectiveness of your campaigns, all while strengthening your brand recognition.
- Enhanced Call Tracking and Analytics: With DID numbers, each department can obtain segregated analytics & track all the calls, and use them to make informed decisions regarding resource allocation and customer service improvements.
- Greater Flexibility and Mobility: When taking remote work into consideration, these can particularly be beneficial, as with DDI numbers, employees can continue to be productive and receive important customer calls via dedicated lines.
What are the drawbacks of DDI numbers?
You now know all the advantages of having DDI numbers for your business, but now it’s time to learn its drawbacks. And just like all man-made things, DDI numbers come along with a good number of those.
Here are some of the most commonly encountered ones:
- Complexity: Setting up and implementing Direct Inward Dialing numbers can be more complex than traditional phone lines and may require technical expertise or support.
- Reliability: DDI numbers are VoIP based and hence completely rely on the Internet for their working. Thus, you may face interruptions in case of internet issues or power outages.
- Scalability: Though these numbers offer some form of scalability, they are not the best solutions for rapidly growing businesses that often make changes to their telephony systems.
- Security: DID/DDI numbers can be vulnerable to spam and security breaches if not properly configured, as they expose internal phone systems to the public.
- Compatibility: You have to have an up-to-date telephony system to use these numbers. Also, DDI numbers are not compatible with all existing phone systems or networks.
