Never miss calls and faxes again. The SprachBox Pro App is the ideal companion for when you’re on the go. For example, all messages that were left on the answering machine at home or in the office are sent directly to the smartphone or tablet and clearly displayed. You can listen to voicemails in any order and call back immediately. Additionally, it is possible to set up call forwarding and to record a greeting message directly in the app. The SprachBox Pro App is a free service for all Deutsche Telekom customers with an IP-based fixed-line connection.
