Uninstall SwitchVox to work with Asterisk in Centos 5


Well with this situation, I have to uninstall the Switchvox and work with asterisk pure.

I have a question: How can I uninstall Swtichvox on my laptop to install CentOS 5.

I have tried several times and I can not install another OS.

Switchvox have any uninstall option?

Thank you for your attention and answers.

Good day.
