DID Services

DDI Gateway provides DID access numbers for worldwide destinations. DID (Direct Inward Dialing also calls DDI in Europe) is a feature offered by telephone companies for use with their customer’s PBX system or VoIP gateway or Softswitch. In DID service, one or more SIP trunk (virtual trunks) is provided to the customer and a range of numbers are allocated to these lines by the telephone company. All calls to such numbers are then forwarded to customer’s VoIP equipment via the VOIP trunks. The DIDs are reachable from any landline or cell phones from across the world.

 We are covering most of the destinations on world wide with best quality.Some zones may require subscriber information before DID service is activated.All customers are solely responsible for the operation of their own business, for complying with any applicable legal and regulatory provisions, and for applying and obtaining any required license(s).

We recommend that customers seek advice on any legal questions, regulatory obligations, and restrictions before using DID numbers.
