A method and scrambling module for degrading delay-sensitive traffic quality in a telecommunications network, wherein data packets that meet a pre-defined rule are detected and delayed by inducing a delay. The scrambling module comprises an access list comprising the pre-defined rule(s) for detecting certain data packets, a packet detector configured to detect the data packets that meet the pre-defined rule, and a delay inducer module acting to induce a delay to the data packets. The delay is variable for consecutive data packets and may follow a seesaw-like function, a random function, or any other type of function for consecutive data packets. The data packets are detected based on the rule, which may contain indications for intercepting the data packets based on their origination from a certain application port number, destination to a certain application port number, origination from an address identified in the pre-defined rule, or destination to a certain address.
