6、Dialed Digit Extraction Event Reporting, is modified as shown below: In IMS-based VoIP, when the intercept subject dials or signals digits in the VoIP content stream after the session is connected to another TSPs service for processing and routing, the TSP shall isolate and report to the LEA the dia
7、led or signaled digits, when reasonably available, as CII to the LEA. The TSP that reports the CII dialed digit extraction information is not obligated to assure that the connection is with another TSPs service. The TSP shall support a dialed digit extraction ATIS-0700005.a 2 capability, with a togg
8、le feature that can activate/deactivate this capability (per lawful authorization) and report the dialed or signaled digits, when reasonably available, as CII. See Annex F of 678 for additional information. The following message is used for the Dialed Digit Extraction (DDE) event reporting: DialedDi
9、gitExtraction NOTE 1 - The CII Dialed Digit Extraction event reporting is not required for other IMS-based multimedia services. NOTE 2 - The session that is connected to another TSPs service for processing and routing, may be provided by the same TSP. ATIS-0700005.a 3 3 ASN.1 DEFINITIONS Annex B, IM
