SIPREC is limited to SIP-established sessions (audio, video, DTMF and real-time text). It does not natively support the interception of non-SIP communications, the generation of structured metadata in ETSI IRI format, or the management of interception orders. ETSI LI, by contrast, covers the entire telecommunications stack \u2014 voice, data, SMS, VoLTE, IMS, and increasingly 5G services \u2014 and provides a comprehensive framework for managing the full interception lifecycle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Architecture differs substantially. SIPREC uses a two-party model (SRC and SRS) with a relatively simple session duplication mechanism. ETSI LI uses a multi-component architecture: points of interception in the network, an administration function that provisions them over X1, a <a href=\"https:\/\/ic-services.io\/ja\/%e8%a3%bd%e5%93%81\/%e3%82%bd%e3%83%95%e3%83%88%e3%82%a6%e3%82%a7%e3%82%a2%e3%83%bb%e3%82%bd%e3%83%aa%e3%83%a5%e3%83%bc%e3%82%b7%e3%83%a7%e3%83%b3\/li%e3%83%a1%e3%83%87%e3%82%a3%e3%82%a8%e3%83%bc%e3%82%b7%e3%83%a7%e3%83%b3%e3%83%bb%e3%83%97%e3%83%a9%e3%83%83%e3%83%88%e3%83%95%e3%82%a9%e3%83%bc%e3%83%a0\/\">mediation and delivery function<\/a> that receives X2\/X3 and hands over to the LEMF on HI2\/HI3, and HI1 for orders. The ETSI architecture is designed to support complex network environments, multiple concurrent intercepts, and the separation of administrative, metadata, and content delivery functions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Security and confidentiality requirements are fundamentally different. SIPREC is designed so that participants can be told that they are being recorded (RFC 7866 recording indications), and its RFCs explicitly exclude lawful intercept. LI requires the opposite: no party to the call may be able to detect the interception (ETSI TS 101 331). In enterprise environments, recording is typically disclosed and may even require the consent of the parties. ETSI LI, on the other hand, includes strict requirements for the confidentiality of the interception \u2014 the target must not be aware that their communications are being intercepted. This requires careful design of the interception point, the delivery infrastructure, and the administrative processes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u6cd5\u7684\u80cc\u666f\u3082\u7570\u306a\u308b\u3002SIPREC\u306f\u3001\u9332\u97f3\u304c\u30c7\u30fc\u30bf\u4fdd\u8b77\u6cd5\u3001\u96c7\u7528\u6cd5\u3001\u6d88\u8cbb\u8005\u4fdd\u8b77\u6cd5\u306e\u9069\u7528\u3092\u53d7\u3051\u308b\u53ef\u80fd\u6027\u306e\u3042\u308b\u3001\u5546\u696d\u7684\u304b\u3064\u898f\u5236\u7684\u306a\u74b0\u5883\u3067\u904b\u55b6\u3055\u308c\u3066\u3044\u308b\u304c\u3001\u6cd5\u57f7\u884c\u6d3b\u52d5\u3067\u306f\u306a\u3044\u3002ETSI LI\u306f\u3001\u508d\u53d7\u304c\u88c1\u5224\u6240\u307e\u305f\u306f\u305d\u306e\u4ed6\u306e\u7ba1\u8f44\u5f53\u5c40\u306b\u3088\u3063\u3066\u8a8d\u53ef\u3055\u308c\u3001\u7279\u5b9a\u306e\u6cd5\u7684\u4fdd\u8b77\u63aa\u7f6e\u3001\u76e3\u8996\u30e1\u30ab\u30cb\u30ba\u30e0\u3001\u304a\u3088\u3073\u6a5f\u5bc6\u4fdd\u6301\u8981\u4ef6\u306e\u5bfe\u8c61\u3068\u306a\u308b\u3001\u6cd5\u57f7\u884c\u306e\u30b3\u30f3\u30c6\u30ad\u30b9\u30c8\u3067\u52d5\u4f5c\u3057\u307e\u3059\u3002.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">SIPREC\u304cLI\u306b\u4f7f\u3048\u308b\u3068\u3053\u308d\u3068\u4f7f\u3048\u306a\u3044\u3068\u3053\u308d<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">SIPREC\u3068ETSI LI\u306e\u9055\u3044\u3092\u8e0f\u307e\u3048\u308b\u3068\u3001SIPREC\u3092 <a href=\"https:\/\/ic-services.io\/ja\/%e3%82%bd%e3%83%aa%e3%83%a5%e3%83%bc%e3%82%b7%e3%83%a7%e3%83%b3\/%e5%90%88%e6%b3%95%e7%9a%84%e3%81%aa%e5%82%8d%e5%8f%97\/\">\u5408\u6cd5\u7684\u306a\u901a\u4fe1\u508d\u53d7\u30bd\u30ea\u30e5\u30fc\u30b7\u30e7\u30f3<\/a>? The answer is nuanced. SIPREC can potentially be used as a media capture mechanism within the operator&#8217;s network \u2014 that is, as a non-standard point of interception that captures the target&#8217;s voice streams. However, SIPREC alone is not sufficient for lawful interception compliance. It must be supplemented with additional components that provide ETSI-compliant IRI generation, secure handover to the LEMF via HI2 and HI3, <a href=\"https:\/\/ic-services.io\/ja\/%e8%a3%bd%e5%93%81\/%e3%82%bd%e3%83%95%e3%83%88%e3%82%a6%e3%82%a7%e3%82%a2%e3%83%bb%e3%82%bd%e3%83%aa%e3%83%a5%e3%83%bc%e3%82%b7%e3%83%a7%e3%83%b3\/%e5%90%88%e6%b3%95%e7%9a%84%e5%82%8d%e5%8f%97%e7%ae%a1%e7%90%86%e3%82%b7%e3%82%b9%e3%83%86%e3%83%a0\/\">\u4ee4\u72b6\u7ba1\u7406<\/a> HI1\u3092\u901a\u3058\u3066\u3001\u304a\u3088\u3073\u6cd5\u5f8b\u3067\u7fa9\u52d9\u4ed8\u3051\u3089\u308c\u3066\u3044\u308b\u6a5f\u5bc6\u4fdd\u6301\u63aa\u7f6e\u306b\u5f93\u3063\u3066\u3002.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, some operators use SIPREC as a media capture mechanism within their IP voice infrastructure, with a mediation function that receives the SIPREC recordings and transforms them into ETSI-compliant handover data. This approach can be effective, particularly in environments where SIPREC is already deployed for enterprise recording and the operator wants to leverage existing infrastructure. If SIPREC is used this way, the SRC must not send recording indications to the parties, the recording server must sit inside the LI-only security domain, and the standardised alternative (X2\/X3 per ETSI TS 103 221-2 from the SBC or IMS element) should be preferred where the equipment supports it. However, the mediation function must handle the conversion of SIPREC metadata to ETSI IRI format, the addition of missing data elements, the secure delivery to the LEMF, and the management of timing and correlation.<\/p>\n\n\n\n<p
