Extension dialing
When extension dialing, the dialer dials one number on demand for each extension. Extension dialing explains the implementation of ISampleManagementProvider_Get for the UNICOM Intelligence Dialer.
If you want to support both extension and group dialing, you must register two dialing providers during installation. The sample code includes both extension and group dialing providers where the extension dialing code is mostly a subset of the group dialing.
