I have installed Avaya IP Office in 3 of my customers sites. They also have requested TAPIT Call accounting software to be added. We are having a problem getting it to send out information. Their corporate office installed the Windows XP Professional on the PC but we are wondering since it is their version with some restrictions that is causing it to fail. We have installed the Merlin Magix previously and the TAPIT is working on all those. Any information would be greatly appreciated.
