Presently have an old laptop running software for the Spectralink 3000 system and trying to move it over to XP. The computer I have is an HP dc7900 Ultra-Slim. Software is on the XP box, both for the USP and Spectralink but when I try to use the Spectralink software to dial out it does not see the fax modem. However I know the fax modem works because I dialed out using putty. I have changed the COM1 ports within the computer and the Spectralink software and nothing. Polycom/Spectralink states it is an IS/IT issue. Any ideas?
