And >please make sure the DLLs of the IPP runtime is in your system path. I've install the IPP runtime component on the second machine and it works fine. Is it necessary to install the IPP runtime component to all the machine where my softphone has to be run?, or is there any other alternatives. If I am going to install the IPP runtime components to all the machine, where my softphone has to be run, please tell me the simplest way so that I can install my IPP runtime component along with my softphone without any manual installation of the IPP runtime component.
