Switch Integration Concepts

Switch integration refers to the sharing of information between a voice messaging system and a switch in order to provide a seamless interface to callers and subscribers. A fully integrated voice messaging system uses information taken directly from the switch to determine how to process each incoming phone call. (Refer to Figure 1-2.)Integrating the Intuity system and a MERLIN LEGEND switch does not require special equipment — the MERLIN LEGEND system sends call information by touch-tones over the same voice circuits used for call processing.
