Methods, systems, and computer readable media for routing of packets for lawful interception

A method for routing of packets for lawful interception, the method comprising:

• forwarding, by at least one session border controller (SBC), a plurality of media streams to a forwarding function implemented on a centralized node for a telecommunications network;
• receiving, by the forwarding function, 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;
• sending, by the at least one SBC and 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;
• and
• performing, by the forwarding function and in response to receiving the first packet, 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.

One or more non-transitory computer readable media having stored thereon executable instructions that when executed by one or more processors of one or more computers control the one or more computers to perform steps comprising:

• forwarding, by at least one session border controller (SBC), a plurality of media streams to a forwarding function implemented on a centralized node for a telecommunications network;
• receiving, by the forwarding function, 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;
• sending, by the at least one SBC and 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;
• and
• performing, by the forwarding function and in response to receiving the first packet, 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.
