Glossary

Determines the switching and signalling to support Integrated Services Digital Network (ISDN) Message Service. ISDN Message Service is a collection of features used to assist a Message Storage and Retrieval (MSR) System in providing call coverage for and notification of waiting messages to its clients users.
