System and method of triggering services for call control

摘要

A system and method of facilitating server-based call processing services and call control may employ service triggers transported via a standard protocol. A service trigger may enable a service provider to modify or otherwise to customize the behavior of a call processing server arrangement; some or all of the functionality of the call processing server arrangement may be controlled or influenced in accordance with parameters set by the service provider and defined by the service trigger. A service trigger may enable a full range of customization options, ranging from simple modifications to complete service creation and implementation, interrupting and altering call control logic at any point during call control operations.
