Asterisk & openvxi

I have been trying to develope and custmize OpenVXI for my project about Call Center. I know that openVXI is not related to this forum but i don’t know from where to begin.
I have 2 questions :

  1. can I run openVXI stand alone ? if the answer is no then how can I test it when i’m trying to customize and develope it ?
  2. What’s difference between VXML browser and VXML interpreter ?
    thanks in advance.
