In this article, we assume that you are using the device-dependent caller ID (CLIP no screening) in the customer portal, and that your PBX / device transmits the information to be signaled for your call.

The user-defined specific caller ID in the customer portal and that of the Cloud Telefonanlage offer a slightly reduced range of functions: Currently, Austrian or other European numbers cannot yet be displayed this way.

Which phone numbers can be displayed?

In general, you may only display numbers that have been assigned to you or for which you are the subscriber. These can, for example, originate from another connection under your name.

In Austria, the maximum number length including the country code is 12 digits.

Call numbers that are prohibited by the regulatory authorities are not permitted by our infrastructure. These include, for example, special numbers, value-added services and emergency numbers. The following is a list of the most common number ranges and a note on whether they are permitted or blocked.
