Number types
Four kinds of number
Availability depends on the country. Each country page lists what is offered.
Geographic
Tied to a city or area code. The usual choice for a local presence.National
Non-geographic numbers that read as national rather than tied to one city.Mobile
Mobile-range numbers where regulators allow them on VoIP. Some support SMS separately.Toll-free
Free for the caller, inbound cost to you. See toll-free numbers.
Delivery
What arrives at your PBX
Inbound calls arrive as a standard INVITE to the address you set, with the dialled number in the Request-URI in E.164 format. Match on that number in your inbound route or DID table.
Whitelist our signalling addresses on your firewall and keep SIP ALG off. Setup steps for each PBX are in the guides.

FAQ
DID number questions
Why do some countries ask for documents?
Regulators in many countries require operators to know who holds each number. Typical requests are a name, an address in the country or region, ID and sometimes business registration. Each country page shows whether KYC is usually required.
How are inbound calls delivered?
To a SIP URI or IP address you set, in E.164 format. You can point each number at a different PBX or route several numbers to one trunk.
Can I use a DID as my outbound caller ID?
Yes, where the country allows it and the route supports CLI. Using a local number you hold is the cleanest way to present a valid caller ID.
Can I port my existing numbers?
Porting depends on the country and current provider. Send sales the numbers and we confirm what is possible before you order.
How many simultaneous calls can a DID take?
Inbound capacity is set at the account level, not per number. Tell sales your expected peak so channels are sized for it.
