Annex B - Example message sequence diagrams

Signalling interworking between "QSIG" and "H.323" in support of the call transfer supplementary services within a Corporate telecommunication Network (CN). "QSIG" is a signalling protocol that operates at the Q reference point between Private Integrated Services Exchanges (PINX) within a Private Integrated Services Network (PISN). "H.323" is a set of signalling protocols for the support of voice or multimedia communication within a packet network, in particular a packet network that used the Internet Protocol (IP) as its network layer protocol (IP network).
