Method of operating a telecommunications link between two telecommunications devices which transmits display control commands in a separate data channel

A method for operating a communications link between an answering device and a telecommunications terminal, which comprises the steps of:

• establishing a communications link to a caller of the answering device by setting up a connection of a voice channel and a data channel;
• transmitting voice information in the voice channel;
• transmitting display control commands in the data channel separate from the voice channel as data signals for triggering a display on a screen of the telecommunications terminal receiving the display control commands, by the steps of:
• transmitting, via the answering device, a command to the telecommunications terminal resulting in a triggering of an automatic response of the telecommunications terminal to request a predetermined display content from the answering device;
• transmitting, via the answering device, the predetermined display content to the telecommunications terminal after receiving the request for the predetermined display content in the answering machine;
• and
• transmitting the display control commands without a dependency on network addresses or internet protocol addresses as the display control commands are transmitted in the separate data channel after the communication link has been established.
