What is a DID (Direct Inward Dialing) Number?

DID numbers (sometimes referred to as SIP trunk numbers) are virtual phone numbers that allow you to route calls to your existing phone lines. Without the requirement for several physical telephone lines, DID numbers are utilized to assign direct numbers to certain members of the team. They’re intelligent phone numbers that can help you manage calls the way you want.

In India, the most common use for businesses using DID numbers is to route incoming consumer calls. When a consumer phones the company, they are greeted by an IVR system that asks who they want to speak with and routes their call to the appropriate employee depending on their answers. DID numbers make it easier for businesses to analyze the number of calls missed, an agent’s response time, time spent on the phone, and client call records for performance analysis.

Direct Inward Dialing (DID) on VoIP

With the use of SIP trucking, VoIP is the most current and flexible approach to using virtual direct-dial numbers. The trunk line connections are made accessible when needed via SIP. These aren’t physical lines; instead, they’re virtual broadband cables that you can use only when you need them.

Internally, these virtual links are configured, and a software application links the numbers to your extensions. You can do it yourself or have it done for you by your VoIP provider.

DID over VoIP is a very scalable solution. For example, if you decide to launch a sales campaign next month that necessitates the addition of 20 new trunk lines, you may simply accomplish this. There’s no need to call your phone company, wait for a block of numbers to be assigned, and then have a technician come out to physically connect the trunk lines to your corporate PBX.

DID numbers work by forwarding all incoming calls to a personal line. It can be a VoIP (Voice over Internet Protocol) line, a mobile phone line, or even a landline. DIDs are gaining traction in the market, especially among businesses, because they provide the sense of having a physical presence in a certain location. The physical office might or might not exist. Callers in the area where the DID number is situated will be charged the same rate as if they dialed another local number.

Traditional Telephone Number Identities vs. DID Number Purchasing.

It’s necessary to understand how phone systems have evolved to fully comprehend how DID number purchasing works.

POTS, which stands for “plain old telephone system,” is a colloquial term for the traditional phone network. only need to be unique inside each area code. As a result, a person in Miami may have the same phone number as a person in Los Angeles. Adding the area code, on the other hand, makes each of those numbers unique.

There are notable exceptions, as several nations share country codes. Nearly every country has its own unique telephone number writer. The International Telecommunication Union (ITU), a United Nations organization, assigns country and region codes according to the E.164 scheme. The plan makes no demands on how each country or country code zone organizes its pool of numbers; the only restriction is that no telephone number exceeds 15 digits in length. The United States is one of just a few countries without a unique country code. Several nearby countries, notably Canada and Caribbean nations like the Dominican Republic, utilize the same “1” code as the United States.

The North American Numbering Plan Administration (NANPA), which is part of the Federal Communications Commission, is the source of all US phone numbers (FCC). NANPA assigns phone numbers in 10,000-block increments or, on occasion, in 1,000-block increments.

Those blocks of numbers are only accessible to registered telecom firms. Telecom companies purchase these blocks to distribute them to their clients. DID number providers, on the other hand, buy blocks of numbers from NANPA and sell them to internet telephony providers in smaller groups, making DID numbers available to consumers and businesses.

How to choose the best DID provider?

You may not be able to choose your DID provider directly as an end-user. DID numbers are sold to VoIP service providers and traditional telecom providers, and you would contact them to sign up for service. You’ll be able to choose the number of virtual numbers you require as well as their area codes during the account setup procedure.

If you want vanity numbers that spell out a word on a keypad or 1-800 toll-free numbers, check sure any VoIP service or telecom company you’re considering has them. If you don’t, the first step is to decide the country and area code you want your phone number to be in.

How do customers choose which is the best DID number?

If you conduct research on a firm and discover that it lacks phone numbers in the places you require, you are unlikely to register an account with that company. In reality, when you reject a VoIP or traditional telecom service, you are also rejecting the DID number provider linked with it.

In some situations, a service provider may not have direct access to the numbers you require but may be able to obtain them through another DIDs supplier. So, if you have your heart set on one provider but aren’t sure if they have the features you require, it’s always worth asking before dismissing them.

Companies that provide DID numbers select their providers based on a variety of factors, including the availability of numbers and the method for provisioning them. Although pricing is usually a consideration, the number range should also be considered. Don’t assume that just because one VoIP or traditional telecom service fails to deliver the DIDs you require, others will as well.
