ITU-T H.450.7 (03/2013)

Message waiting indication supplementary service for ITU-T H.323 systems
Recommendation ITU-T H.450.7 specifies the procedures and signalling protocol for the supplementary service for message waiting indication (SS-MWI) in ITU-T H.323 (packet-based multimedia communication systems) networks.
The SS-MWI enables a served user to be sent a message waiting indication (MWI) and also enables this MWI to be cancelled. The served user may also be permitted to interrogate a message centre for any MWIs.
The procedures and the signalling protocol of this Recommendation are derived from the SS-MWI as specified in ISO/IEC 15505 and ISO/IEC 15506.
This Recommendation makes use of the "Generic functional protocol for the support of supplementary services in ITU-T H.323 systems" as defined in Recommendation ITU-T H.450.1.
This revision introduces editorial and technical changes, clarifications and corrections, in particular those indicated in the Implementers' Guide for Recommendations of the ITU-T H.323 system (2011).
