Austrian business calling

A few things
worth knowing.

Can I get an Austrian business phone number?

Yes. Explore the Austrian number selection in your account for incoming business calls. The current catalog shows available options.

Are all Austrian numbers linked to a city?

No. Austria also has location-independent number ranges such as 0720. Check the type of the number you choose; the +43 country code alone does not identify a city.

Can I call Austrian landlines and mobiles?

Yes. IllyVoIP provides outbound voice to supported Austrian landline and mobile destinations, alongside incoming calls to your active number.

Can colleagues use different calling devices?

Your team can use IllyVoIP for Windows, iOS and Android, the browser webphone or a compatible SIP setup with the appropriate calling service.

Can developers create a custom calling experience?

Yes. The Voice API offers call-control actions and webhooks for supported outbound calls and eligible incoming numbers.
