What is a DID number?
A DID (direct inward dialing) number is a phone number that routes incoming calls directly to a specific endpoint on your phone system, without a separate physical line for each number. Calls arrive over a SIP trunk or the internet, so one connection can carry hundreds of numbers to your PBX, softswitch, or contact center platform.
didlogic DIDs are an integrated SS7-SIP product: the same local carrier connection carries inbound and outbound calls with the native caller ID, so outbound calls show the same local number your customers dial. In 17 countries the service runs on a licensed local voice model, supporting emergency calling and short-code dialing like a national telephone provider.
FAQ
What is the difference between DID numbers and traditional phone numbers?
DID numbers are virtual and do not require physical lines, unlike traditional numbers. They route calls through internet-based systems, making them more flexible and cost-effective. Read our guide to learn more.
How much does a DID number cost?
Cost is set by country and number type and always has two parts: the monthly fee and the inbound per-minute charge. At the low end, local DIDs run from $0.99 per month with inbound from $0.001 per minute, and many countries offer flat-rate channel billing instead of metered minutes. Exact figures per country are on the pricing page.
Can I use DID numbers for international business operations?
Yes. DIDs let you hold local numbers in multiple countries and answer every call on one system, which is how global businesses establish a local presence without local offices.
Can DID numbers support SMS messaging?
Yes, inbound and outbound SMS is available on selected numbers.
Are DID numbers compatible with my existing phone system?
Most likely. didlogic supports integration with FreeSWITCH, Asterisk, Avaya, Cisco, and other SIP-based PBX systems, with built-in support in 3CX.
How quickly can I set up DID numbers?
In-stock DIDs are usable the moment you assign a destination after purchase. Where a country’s regulator requires documentation, the number activates once the paperwork clears; the portal shows each number’s requirements up front so there are no surprises.
Are there limits to the number of simultaneous calls on a DID number?
No. didlogic’s scalable channel capacity can support hundreds of simultaneous calls, depending on your configuration.
How can DID numbers improve customer experience?
Local or toll-free numbers make it easier and cheaper for customers to reach you, and native caller ID means your outbound calls show the same local number they already know.
What industries benefit most from DID numbers?
Customer service, e-commerce, healthcare, and distributed teams benefit most from the flexibility and cost savings of DIDs.
