A few things
worth knowing.

A local number uses the area code associated with a Dutch locality. An 085 number gives your business a national contact without a city area code.
Can I make and receive business calls?
Yes. Use your Dutch number for incoming enquiries and IllyVoIP outbound voice to call supported Dutch landline and mobile destinations.
Can I use my existing SIP phone system or IllyVoIP apps?
Yes. Connect a compatible PBX or SIP device, or use IllyVoIP apps for Windows, iOS and Android. The browser webphone provides another way for your team to call.
Can I connect Dutch calling to my application?
Yes. Use the Voice API for custom call workflows, with call-control actions and webhooks. Incoming workflows use eligible numbers and outbound calls use supported destinations.
