Problem

Errors occur when the Cisco IP SoftPhone application is installed on a new (not an upgrade) installation of Windows XP Professional with a non-compatible version of SoftPhone. Cisco IP SoftPhone will not launch after the installation. The splash screen displays for only one second and ciscoipsoftphone.exe does not run.

The following two error messages display during the Cisco IP SoftPhone installation:

DirectX Media 6.0 Error: This package is meant for professional 
redistribution only <OK> 

Warning: Please note that Service Pack 1 is a pre-requisite for the Windows 
2000 JVM hotfix. The hotfix will not be installed.

Solution

Cisco IP SoftPhone version 1.2(3) or later is required for Windows XP. You can download this version from Voice Software (registered customers only) in the Downloads .

Important: Disabling the personal firewall component of Windows XP is recommended. There may be problems processing Real-Time Transport Protocol (RTP) packets if the personal firewall is enabled. See Windows XP documentation for additional information.
