- YacClientService: windows service, listens on port 10629 (this
port will have to be opened on your machine if you use a software
firewall product) for caller id notices from the YacServer application (
http://sunflowerhead.com/software/yac/).
- YacClientListener: windows form, runs in the taskbar and
waits for messages from the YacClientService. The installer will add a
shortcut to the Startup folder, this application is just a listener so
if you don't want it to run just delete the shortcut.
Both of these apps only need to be installed once per machine.
