scope:
The present document provides the ETSI endorsement of the 3GPP TS 29.163 (V7.1.0) [1].
The clauses 7.2.3 and 7.4 of 3GPP TS 29.163 [1] specify the signalling interworking between ISDN User Part (ISUP) protocols and SIP in order to support services that can be commonly supported by ISUP and SIP-based network domains.
The clause 9.2.3.3.5 specifies how ringing tone is applied at the gateway when interworking ISUP and SIP.
The present document specifies the principles of interworking between the ETSI TISPAN IMS and ISUP based legacy CS networks, in order to support IM basic voice calls, therefore all the references to interworking between IMS and BICC are out of scope of the present document.
The present document is a protocol interworking specification; therefore all references to the user plane interworking are out of scope of the present document.
The present document specifies the interworking between ETSI SIP profile (as specified within ES 283 003 [3]) and ISUP, as specified in EN 300 356-1 [2] respectively.
