What is Direct Inward Dialing? DID phone numbers 101
DID stands for Direct Inward Dialing and is often used interchangeably with “telephone number”. DID is a service provided by a local exchange carrier (LEC) that allows a phone call to ring to a direct line rather than having to pass through a phone tree or menu in order to be routed to its end location. The term originates from a time when it was more common for offices to avoid individual phone numbers for employees, and instead utilize extensions. Now, businesses can offer individual phone numbers for its employees without requiring different lines into the private branch exchange (PBX). A DID may also be used for inbound faxes and VoIP communications as well.
Why do businesses use DID?
Businesses are utilizing DID services as an easier way for their customers or clients to gain access to direct lines rather than being interrupted by an operator, placed on hold or navigating a phone menu upon calling. In turn, yielding a higher user/customer experience level.
DID numbers can offer a local numbers for your business regardless of whether you’re physically in the local community or not, as DID numbers are not restricted by geographical location. Implementing local DID numbers can increase a business’s probability of calls reaching potential customers as businesses typically prefer to work with other businesses in the area. Local DID numbers provide a personalized touch along with a higher level of comfort to the recipient of the call.
Some businesses are even using DID services for fax servers, allowing many of those users to have their own individual fax numbers. VoIP vendors will sometimes use a fax server to offer these communication services to their clients, since DID services have similarities to that of VoIP communications.
How much does DID cost?
DIDs vary in price depending on the carrier you’re using, or the re-seller you what to purchase from, the type of DID you’d like (toll-free, international, etc.) and the country the DID will be based in.
Bandwidth’s DID price is $0.35 per line per month.
Where can I get DIDs?
DID services may be purchased through any LECs or competitive local exchange carriers (CLECs). In countries that have a competitive market for local number providers, CLECs may sell DID services to businesses in bulk.
You can also purchase a DID through a VoIP provider. VoIP companies buy millions of phone numbers every month in major cities around the world. Being that VoIP numbers are not tied to a specific area code, if you purchase a DID through a VoIP provider, you will have a local number for any area code you’d like, and you can purchase as many as you’d like.
