DID numbers

DID (Direct Inward Dialling) Numbers or Virtual Numbers (also called DDIs in Europe) are local telephone numbers for a selected country or city. The calls made to these numbers are then forwarded by Top Connect to Voice-over IP (VoIP). A company can use one DID to route all of their inbound calls directly to particular contacts within a company without the need for extra physical phone lines or without the need for the caller to be routed through menu options, etc.

The Advantages of DID Numbers

Possessing a DID number can be beneficial in a variety of ways.

You can make use of the DID number for live voice connections as well as for fax and voicemail. DID will help to save on the cost of a switchboard operator.

A DID is good for business as those who call your DID number can be “put through” to the desired contact more efficiently without the need for an intermediary such as a switchboard, call waiting or menu system, etc. 

You are able to establish a local presence in any location you choose. This helps customers to get in touch with you for the cost of a local call.

Companies with multiple international locations can greatly cut costs by making use of a DID number.

Virtual SMS-Enabled DID (MSISDNs)

Virtual SMS-Enabled DID numbers require high investments from mobile network operators (MNOs) and therefore many companies are providing virtual mobile numbers (DID) without SMS capability.

Top Connect has a unique technology* to convert any mobile numbers (MSISDNs) which have no inbound SMS connectivity into SMS-enabled numbers (MSISDNs).

For whom is this solution useful?

  • For aggregators, DID number providers
  • For mobile network operators (MNOs)
  • For businesses who need to receive SMS to their mobile numbers (but local MNOs can´t provide it)


Benefits of Top Connect SMS-enabled DID numbers:

  • easy to set up;
  • easy to use;
  • no capex investment into the mobile network; 
  • unlimited amount of numbers
