RemarksTelephony system is represented as a set of TapiLine objects, each with one or more addresses. Addresses collection lists TapiAddress objects representing addresses (phone numbers or extensions) associated with the line. Most systems have one line for each phone number or extension, with one address on each line.
AddTapi.NET creates a TapiLine object for each telephony line device installed on the computer. The application can subscribe to LineAdded and LineRemoved events to receive notifications when a line device is added or removed.
