active, Most Current
Organization: ITU-T
Publication Date: 1 May 2011
Status: active
Page Count: 74
scope:

This Recommendation specifies the diversion supplementary services (SS-DIV), which comprise the services Call Forwarding Unconditional (SS-CFU), Call Forwarding Busy (SS-CFB), Call Forwarding No Reply (SS-CFNR) and Call Deflection (SS-CD), all of which are applicable to various basic services supported by H.323 endpoints.

NOTE - The concept of basic services in the context of H.323 is for further study.

SS-CFU, SS-CFB, SS-CFNR and SS-CD are supplementary services which apply during call establishment providing a diversion of an incoming call to another destination endpoint.

SS-CFU, SS-CFB, SS-CFNR and SS-CD are supplementary services which apply to point-to-point calls. An incoming call via multicasting may be subject to call diversion.

This Call diversion supplementary service is based on ISO/IEC 13872 and ISO/IEC 13873.
