<p>This International Standard specifies signalling interworking between "QSIG" and "H.323" in support of call diversion</p>
<p>supplementary services within a Corporate telecommunication Network (CN).</p>
<p>"QSIG" is a signalling protocol that operates at the Q reference point between Private Integrated Services eXchanges (PINX)</p>
<p>within a Private Integrated Services Network (PISN). The Q reference point is defined in ISO/IEC 11579-1. A PISN provides</p>
<p>circuit-switched basic services and supplementary services to its users. QSIG is specified in other Standards, in particular</p>
<p>ISO/IEC 11572 (call control in support of basic services), ISO/IEC 11582 (generic functional protocol for the support of</p>
<p>supplementary services) and a number of standards specifying individual supplementary services. ISO/IEC 13873 specifies the</p>
<p>QSIG protocol in support of call diversion services.</p>
<p>"H.323" is a set of signalling protocols for the support of voice or multimedia communication within a packet network, in</p>
<p>particular a packet network that uses the Internet Protocol (IP) as its network layer protocol (IP network). H.323 signalling</p>
<p>protocols operate between endpoints in an IP network, either indirectly via one or more gatekeepers, or directly. An endpoint</p>
<p>can be a terminal or a gateway to another network. H.323 is an "umbrella" recommendation referring to various ITU-T</p>
<p>recommendations, in particular Recommendations H.225.0 and H.245 (basic communication capabilities) and</p>
<p>Recommendation H.450.1 (generic functional protocol for the support of supplementary services). Recommendation H.450.3</p>
<p>specifies the H.323 protocol in support of call diversion services.</p>
<p>NOTE - H.450.3 applies only to the 1998 version of H.323 (also known as H.323 version 2) and to later versions.</p>
<p>In both ISO/IEC 13873 (QSIG) and ITU-Recommendation H.450.3 (H.323), the call diversion supplementary services are Call</p>
<p>Forwarding Unconditional (SS-CFU), Call Forwarding Busy (SS-CFB), Call Forwarding No Reply (SS-CFNR) and Call</p>
<p>Deflection (SS-CD). These supplementary services apply during call establishment and provide diversion of an incoming call to</p>
<p>another destination.</p>
<p>Interworking between QSIG and H.323 permits a call originating at a user of a PISN to terminate at a user of an IP network, or</p>
<p>a call originating at a user of an IP network to terminate at a user of a PISN. This International Standard provides the following</p>
<p>additional capabilities:</p>
<p>_ a call originating from a PISN and destined for a user of an H.323 network to be diverted by the H.323 network to an</p>
<p>alternative destination;</p>
<p>_ a call originating from an H.323 network and destined for a user of a PISN to be diverted by the PISN to an alternative</p>
<p>destination;</p>
<p>_ a call destined for a user of a PISN to be diverted to an alternative destination where that alternative destination is in an</p>
<p>H.323 network;</p>
<p>_ a call destined for a user of an H.323 network to be diverted to an alternative destination where that alternative destination</p>
<p>is in a PISN.</p>
<p>This International Standard is applicable to any interworking unit that can act as a gateway between a PISN employing QSIG</p>
<p>and an IP network employing H.323.</p>
