DID Services

What is a DID (Direct Inward Dialing)?

Direct Inward Dialing (DID) is a phone service that enables a phone number to ring directly to a specific phone at a business rather than going through a menu or queue and dialing an extension.

The Private Branch Exchange of your business is connected to a group of phone numbers through this (PBX). You can place outgoing calls using Direct Outward Dialing from your office phone system.

Pro-tip

Direct inward dialing (DID) is a telecommunication service that provides businesses with dedicated phone numbers that can be used to receive calls directly from customers. For businesses, it can result in faster responses and more efficiency. DID implementation can generally boost customer satisfaction and enterprises' operational effectiveness.

A DID number is a local phone number that is associated with a particular location or nation and is unconnected to an additional physical phone line.

It is similar to any standard telephone number from the client or customer’s perspective. But a DID is a virtual phone number that goes directly to a location or an extension in your company. So you can think of it as a short route to a phone line.

The direct dial phone numbers point inbound calls to a company’s phone system. As the number relays callers to an individual user, it is known as a direct number. The VoIP phone system manages the call routing.

You now know about the direct inward dialing meaning. Next, let’s focus on the other aspects of direct inward dialing.

How DID Number Works?

DID works in one of various ways:

1. Voice over Internet Protocol (VoIP)

2. Public Switched Telephone Network (PSTN)

3. Faxing

4. Private Branch Exchange

5. Primary Rate Interface (PRI)

Direct Inward Dialing on VoIP

VoIP is the most flexible and modern way to implement virtual direct dialing in numbers with SIP trunking. With SIP, the trunk line connection is available when necessary. These lines are virtual links across broadband networks when you need them.

These virtual links are internally configured, and a software application links the numbers to your extensions.

DID VoIP is scalable in nature? For instance, it would be simple for you to conduct a sales campaign next month that requires the creation of 30 new trunk lines. There’s no need to speak with your telephone provider. Wait for them to provide you with numbers and send techs to connect the trunk lines to your company's PBX instead.

In the traditional setup, companies had to wait for weeks, and the cost was also substantial. But, with DID line, VoIP companies can now figure it out themselves.

VoIP systems have multiple features that consume time to learn. However, with most VoIP providers offering professional onboarding and support, it has gotten easier for companies.
