General Notes

...

1. 1. Install Fedora 19 or CentOS 6.6 minimal install.
   2. Only minimum installation is necessary, in fact this is preferred. All packages sipXecs needs will be installed automatically
   3. Be sure to run yum update after installing your OS and before installing sipXecs to ensure the latest RPMs are install but also avoid conflict errors when new packages are getting installed.
   4. CentOS 6 is the preferred distribution because has received the most testing coverage.
   5. 64 bit version of the distribution as it's preferred by MongoDB: the embedded distributed database package.
      NOTES - On CentOS
