DID numbers
Build a local point of contact at a larger scale. Plan number requirements, incoming voice and SIP delivery with a partner that understands your operation.
Direct inward dialing
A DID is a phone number that directs incoming calls to your business telephony setup. It gives a team, location or customer a contact point without a separate physical phone line for each number.
Wholesale starts with the bigger picture: the markets you serve, the number quantities you need, your SIP infrastructure and the incoming call capacity behind them.

What makes a DID request wholesale?
It is planned around larger number requirements, customer or location portfolios, and the voice infrastructure that receives the calls. Pricing and operational terms depend on the scope of the deployment.
Does more DID inventory mean more simultaneous calls?
Not automatically. Number quantity and concurrent call capacity must be agreed separately. Include expected traffic peaks in your request so the configuration can be sized appropriately.
Can I use these numbers as outbound caller ID?
Ask us to confirm the number and route combination. Outbound presentation depends on authorization, destination and route support; it should be tested separately from incoming call delivery.
Do all DID numbers support SMS?
No. Voice and messaging capabilities depend on the specific number and service. Include SMS requirements in your enquiry rather than assuming they are included.
Can I bring existing numbers?
Include the countries, number types and current provider in your request. Any migration or porting option must be checked for the specific numbers before a transfer is planned.
How quickly can a batch be activated?
Lead times depend on inventory, documentation and technical configuration. Confirm availability and the activation schedule with our team before setting a customer launch date.
