Telephone ISDN/analogue / problems with diversions to the public network (mobile working) (beendet)
From: 29.08.2023 / 13:17
To: 08.09.2023 / 18:00
With telephones that are connected to the old ISDN PBX system (Siemens telephones or analogue telephones), it can currently happen that with activated call forwarding to the public network (e.g. mobile working) anonymous calls cannot be put through.

This effect only occurs with some telephones and only if the incoming calls are anonymous, i.e. with a suppressed number.

Forwarding to other inhouse phones is also affected.

VoIP connections are not affected.

A solution to the problem is being worked on.
