Thanks PythonPoole..no i had the call recording software already installed , infact installed a new sound card on the PCI slot (Yamaha) after installing the IVM..pl do let me know the software you are referring to which would allow two programs to access the same application.Would it work if I installed a second CAHTA board..so that each of the softwares could access respective boards..but catch is both have to access same kind of tel lines.
