What Is Direct Inward Dialing (DID)?
A DID service connects an incoming call to the appropriate person without having to go through directory searches or operators. This process is completed by assigning a unique phone number for each staff member so that customers can reach that person directly when they dial in.
With a DID line, users can make virtual calls that are able to bypass the traditional phone system and go directly to the person who is responsible for answering calls. Additionally, customers do not need to remember an extension or PIN code, as these virtual numbers can be programmed to route automatically without any manual intervention.
What is a Direct Inward Dialing Number?
A DID number is a virtual number that allows customers to contact your business without dialing multiple extensions or pins. It’s a 10 or 11-digit number that routes the caller directly to the person or department they are trying to reach. DID numbers can be set up as local, toll-free, international, or for specific area codes.
Essentially, a DID number is a shortcut for callers, connecting the customer directly with the intended contact. It eliminates the need for customers to search for a directory or call an operator to get the right person on the line.
How Does Direct Inward Dialing Work?
There are two main ways that DID works:
- Through Public Switched Telephone Network (PSTN): This is the traditional method of setting up a DID line. The provider will establish a set of numbers to be directed through the PSTN to your Private Branch Exchange (PBX) system.
- Through Voice over Internet Protocol (VoIP): VoIP allows users to set up virtual phone lines using an IP address or cloud-hosted service. This allows for a wider variety of features, such as automated attendant functionality, call forwarding, and recording.
Regardless of which method you choose, setting up DID is easy. Once the numbers have been assigned to your organization or individual, they are ready to be used immediately.
Direct Dialing Using VoIP
VoIP is the most popular option for direct dialing because it offers various features and benefits. With VoIP, you can easily pick a plan that suits your needs without worrying about installation or setup fees. Additionally, VoIP services are typically more affordable and faster than PSTN lines.
Some of the features that VoIP services offer include:
- Automated attendant functionality
- Unified Communications (UC) integration
- Cloud-based call routing
- Voicemail transcription and forwarding
- Advanced call monitoring capabilities
- HD audio quality
VoIP phone providers use SIP trunking to connect the lines to your PBX system, meaning that the virtual numbers are connected directly to your internal phone system. This allows each call to be routed directly to the right person or department without needing manual intervention.
Thanks to this, the most essential benefit of using VoIP is its scalability—you can easily set up a virtual team of experts and ensure that each customer call is answered promptly.
Direct Dialing Using PSTN
PSTN is the traditional method of establishing direct inward dialing. It’s a reliable telephone line that allows customers to dial directly into your company’s PBX system without needing to call an operator or directory.
Traditional phone systems functioned with analog circuitry that was directly dialed, which was both expensive and time-consuming to set up. Furthermore, the hardware invariably created low-voltage signals for the phones so they would work.
The telephone company checked every now and then to see if the line was still in service. If it wasn’t used, they deactivated the circuit. But with the introduction of digital signals, direct dialing has become more accessible and dependable. The customer’s phone still sends low voltages, but these are now converted into bits in order to be transmitted over the phone lines.
Trunks used for DID services can only send, not receive, calls. So, it’s commonplace to also use direct outward dialing (DOD) trunks. Doing so means the direct-dial line can make outbound calls and still retain its allocated DID phone number.
The main benefit of using PSTN for direct dialing is its reliability and stability, as it does not rely on an internet connection. This makes it ideal for businesses that need a nonstop service and are unwilling to take on the risk of poor call quality or dropped calls. Additionally, PSTN lines can be used in tandem with VoIP lines, allowing you to combine the features of both services.
Do I Really Need Direct Inward Dialing Software?
DID services are essential for businesses looking to grow their customer base and ensure that each call is answered promptly. Moreover, they eliminate the need for manual intervention when routing calls, which can be time-consuming and inefficient.
You do not need DID services if:
- You want to use a traditional PBX system.
- You only have a few lines and don’t require complex call routing functionalities.
- Your team doesn’t need to be available 24/7.
But if you want to ensure that your customers can reach you whenever they need and have their calls routed directly to the right person or department, then DID is a must-have. And if you have more than a few employees, direct dialing can help you manage calls more efficiently without needing to hire a dedicated operator.
There are several DID software packages available on the market, ranging from basic to enterprise-level solutions. Depending on your requirements, you can choose a software package that best fits your needs.
VoIP vs. PSTN: Which Is Better for Direct Inward Dialing?
When it comes to direct inward dialing, both VoIP and PSTN lines have their own benefits.
VoIP is the best choice for businesses that need a scalable and cost-effective solution because it offers various features and benefits. With VoIP, you can easily pick up additional lines when needed and enjoy advanced features such as voicemail transcription, automated attendant functionality, and HD audio quality.
With VoIP software, calls take place both on your network and virtually. This means that you won’t need to purchase extra hardware, further saving you money.
PSTN is usually seen as the more reliable and secure option. It’s ideal for businesses that need uninterrupted service without worrying about call quality or dropped connections. This makes it the perfect choice for establishments that require nonstop services, such as hospitals and banks.
That said, VoIP providers are continuously improving their software, and many of the latency and quality issues have been resolved.
Ultimately, the decision between VoIP and PSTN rests on your individual needs. Since VoIP offers a convenient, lightweight, scalable, and cost-effective solution, it is the best option for most. But if you need the reliability and security that some industries require, PSTN might be the better choice.
