Asterisk (small class project)

I would like to install Asterisk (either AsteriskWIN32 or AsteriskNOW) on my PC. I attempted to install each of them over the last couple of days but I have failed to get it working. This is suppose to be a simple class project but it has been anything but that. What I am looking for is; - At least 5 internal phones with a 4 or 5 digit number (any number is OK) - Must be able to use a softphone (x-lite, 3CX, etc) - Must be able to make and receive outside calls via SIP NOTE: I already registered with a SIP provider ([login to view URL]) and I obtained a DID number which I can provide upon our agreement or please provide me instructions on how to set it up. - ACD solution with a main number that prompts basic options such as; 1 for sales, 2 for billing and 3 for technical support. Please provide instructions on how to record and post prompts. NOTE: These options should be able to route the caller to a different SIP device per selection. - Configure basic voicemail I also installed VMware (VMworkstation) on my PC which allows me to run a Linux based OS on Windows XP. So, both AsteriskWIN32 and AsteriskNOW are both OK solutions. I already downloaded and installed both from Asterisk's website and everything is ready for me to apply these conf files. X-lite 4 has been installed but I am unable to register it to Asterisk AND make it dial an outside number. Thank you in advance for your quick response. Mark
