V7.1.0 (PDF)  2011/10  28 p.

Rapporteur:  Mr. Jesske, Roland
See also:  TS 29.527

This TS provides the ETSI endorsement of the TS 29.163 (V7.1.0).

The clauses 7.2.3 and 7.4 of TS 29.163 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 specifies how ringing tone is applied at the gateway when interworking ISUP and SIP.

This TS 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 this TS.

This TS is a protocol interworking specification; therefore all references to the user plane interworking are out of scope of this TS.

This TS specifies the interworking between ETSI SIP profile (as specified within ETSI ES 283 003) and ISUP, as specified in EN 300 356-1 respectively.
