Remarks

This message is sent when a call arrives. An ISDN telephone may answer to several MSN's. Consider, for example, a home office work place. Here there will be one MSN for private calls and one for business calls. At the end of the month, we need to work out what proportion of the calls were for business. The calls can be assigned correctly using the called MSN in m_szMessage.

Another possibility exists in a switch context. A single line may have several internal extensions. 210 may be for normal internal calls and 310 is a hotline connection. m_szMessage would contain either 210 or 310.

TAPIMaster® attempts to discover and signal one of these two values. However, most drivers do not support addresses. What can be signalled depends on what the switch, telephone and drivers support. It is also possible for this event not to be sent at all, or alternatively, to be sent several times during a call.
