You do not have any PBX and would like to install TAPIMaster ® nevertheless, however, on a trial basis? No problem. The Demo TAPI-Treiber emulates a PBX. More TAPI Tools you can find at the TAPIMaster® website.
The TAPIMaster® TAPI Line Watcher allows you to test the TAPI interface without special TAPI knowledge. It can give you a good overview of switch performance when you are buying a PBX and can show you which telephony functions the switch provides.
