VoIP DID Dialing
Receiving Direct Incoming Calls
It's a feature that we take for granted most of the time. Every person has their own unique telephone number through which they can be contacted. If there are many people resident in a given establishment, it's possible for them to have their own number. Otherwise, a single telephone will have to suffice for the mall. One person left. Up and direct it towards whomever it needs to reach. Many old-fashioned businesses still work the same way as they have a receptionist in the lobby who handles the work. With Direct Inward Dialing however, we can get rid of this inefficient system. Each person can have their own extension through which they can be reached independently.
This is especially relevant in a business organization. It's inconvenient to have to know the extension number of every employee. It's much easier for the customer to directly dial the number of whomever they want to talk to. With a traditional phone system, the last few digits of the telephone number are what is used to identify the necessary person. You can replicate this functionality very easily with a VoIP based system. In fact, it doesn't require any complicated setup whatsoever. Everything happens automatically.
DID with VoIP
When you sign up for a hosted PBX system with an SIP provider, every employee of yours will get their own telephone number for a very minimal fee. The system is exceptionally scalable in the sense that there are no limits on the infrastructure as long as you have a proper working Internet connection. The telephone number of every employee can be used to directly contact an employee without going through a receptionist or an extension number. This DID number can be associated with an SIP address that is used to power the VoIP phone. It will appear on all of your outgoing calls – even those which connect to the PSTN system.
Technically speaking, any telephone number used by a VoIP user that connects directly to the device or devices is a DID number. Different Internet telephony service providers or ITSPs have different pricing structures for organizations. You either pay in bulk or individually. These will usually cover all features including VoIP HD voice as part of the hosted PBX package. The infrastructure for setting up a bare VoIP system is very minimal. You can get started in as little as 15 min. Don't hesitate to contact your SIP provider for more details.
