1. A system for routing of packets for lawful interception, the system comprising:
at least one session border controller (SBC), wherein the at least one SBC is configured for forwarding a plurality of media streams to a forwarding function; and
the forwarding function, implemented on a centralized node for a telecommunications network, the centralized node comprising one or more processors, wherein the forwarding function is configured for receiving the plurality of media streams and forwarding each media stream to a respective lawful intercept mediation server for at least one country associated with the media stream;
wherein the at least one SBC is configured for sending, with a first packet of a first media stream, a first direction indicator to the forwarding function, the first direction indicator specifying whether first packet is an inbound initial request or an outbound initial request;
wherein the forwarding function is configured for, in response to receiving the first packet, performing a destination lookup for the first media stream using the first direction indicator and sending a mediation server identifier for the first media stream to the at least one SBC, wherein the mediation server identifier identifies a first lawful intercept mediation server found by the destination lookup.
