Chapter in this post:
I've known about the "call waiting" feature for a while now. However, my (certainly rarer!) analog connection here in the country has a special form of knocking. Normally it only makes a soft “clock clock” in the background when making a call when another call comes in. For me, however, it makes a whopping 5 to 6 seconds of any tone sequences that massively disrupt the ongoing call. Why is this happening to me? No idea. For the first few weeks I didn't even think it was a call waiting signal because it sounds so weird.
Deactivate call waiting temporarily and permanently
For my part, I would prefer the tried and tested busy signal for the other call partner so that my ongoing call is not constantly interrupted. First of all, I had to find out for myself how the deactivation of the call waiting feature works at Telekom. The Telekom-hilft website has explained it, but it didn't quite work for me as it was described there. Only the key sequences were the same. But now for instructions.
Deactivate for a call
If you only want to turn off call waiting for a call, pick up the receiver or press the dial key and then enter this key sequence: * 4 3 #
This means that you will not be bothered by call waiting during the next call.
Incidentally, with my Fritz! Fon I had to enter the key combination and then press the green dial key. Then there was no announcement or the like (as one sometimes reads in other instructions), but a dial tone and the message that call waiting is switched off.
I opted for permanent deactivation and had to use this key sequence for this: # 4 3 #
Switch off with IP connections
If mine has an IP-based telephone connection, you may have to proceed differently. In this case, the "call waiting" feature is probably managed via the router (SpeedPort, Fritz!Box or similar). Unfortunately, I can't show you an exact way now, but in the Fritz!Box you would have to look around in the "Telephony" administration area. There probably under “telephony devices” and then at the corresponding telephone.
