What it is
A DID is a real phone number that routes to your system
DID stands for Direct Inward Dialling: a phone number that rings straight into your phone system, contact center or IVR instead of a physical line. When someone calls the number, the call arrives over SIP at whatever destination you configure.
DIDs matter for outbound calling too. The most trustworthy caller ID you can present is a number you actually own. A local DID in the recipient’s area, presented consistently and answered when called back, is the single strongest signal that your call is legitimate — to people and to the carriers deciding how to label calls.
CLIRoutes offers local geographic numbers, national numbers, mobile numbers where available, and toll-free numbers. Each country has its own rules: some require a local address or business registration, others restrict how numbers may be used. We show those requirements before you buy and collect documents in the portal.
Numbers bought from CLIRoutes are pre-verified for use as caller ID on our CLI, CC and IVR routes, so you can buy a local number and present it on outbound calls the same day.

How it works
How an inbound call reaches you
The caller dials a normal number; the call arrives at your system over SIP.
- Hop 1CallerDials your local, national or toll-free number from any phone.
- Hop 2CLIRoutes number hostReceives the call from the originating network and applies your routing rules.
- Hop 3Your destinationSIP URI, trunk or IVR flow — with failover if the primary does not answer.
- Hop 4Your agent or IVRAnswers the call. The caller’s number is passed through where available.
Failover rules
If your primary destination is unreachable, calls move to a secondary endpoint, another number or voicemail.
Caller ID passthrough
Original caller ID is passed to your system where the originating network provides it.
Same number, both directions
Use the same DID for inbound and as outbound caller ID, so callbacks reach the right team.

Quality metrics
The numbers that matter here
For numbers, quality means callers get through quickly and clearly. These metrics apply to inbound traffic on your DIDs.

Compare
How this route compares
Most customers run two or three route types side by side. Use the one that matches each traffic profile — mixing them on one trunk is the most common cause of poor answer rates.

Rules that keep this route stable
Numbers are a regulated national resource. These rules come from national regulators, not from us.
Address and identity requirements
Many countries require a local address or business registration for geographic numbers. We collect and store documents securely.
Permitted use
Some number types are restricted — for example, mobile numbers may not be usable for outbound calls in certain markets.
Caller ID presentation
When presenting a DID on outbound calls, follow local CLI rules, including STIR/SHAKEN in North America.
Emergency services
Emergency calling availability depends on country and number type. Country pages explain local requirements.

Why owning your caller ID changes outbound results
Recipients answer numbers they recognise and can verify. Carriers trust numbers that are assigned to the caller, answered when called back and used consistently. A DID you own ticks every box at once.
Pair CLIRoutes numbers with our CLI, CC and IVR routes for one verified identity across inbound and outbound. Number pricing and your rate deck are available in the portal after sign-up.
FAQ
DID Numbers FAQ
Can’t find what you need? Our routing team answers within the hour, around the clock.
What is a DID number?
A DID (Direct Inward Dialling) number is a phone number that routes incoming calls directly to your phone system, contact center or IVR over SIP, without a physical line.
Which number types do you offer?
Local geographic, national, mobile (where regulation allows) and toll-free numbers. Availability varies by country and is shown in the portal before you buy.
How quickly are numbers activated?
Numbers without document requirements activate within seconds. Numbers that need address or business proof activate once documents are approved.
Can I use a DID as my outbound caller ID?
Yes. Numbers bought from CLIRoutes are pre-verified for use as caller ID on our CLI, CC and IVR routes.
Can I port my existing numbers?
In most countries, yes. Start a port-in from the portal and we guide you through the required documents and timing.
What documents might I need?
Commonly proof of a local address, business registration or identification. Requirements are set by each national regulator and shown before purchase.
Where can incoming calls be routed?
To a SIP URI, a CLIRoutes trunk, an IVR flow or a forwarding number, with failover rules and time-of-day routing.
Do toll-free numbers work internationally?
Toll-free numbers are usually reachable only from within their own country, and sometimes only from certain networks. Country pages note any limitations.
