How to start receiving phone call?

I just installed the software. I have a phone number from Onesuite VOIP services. It’s working with my ATA. How to use it on the freepbx? I added a trunk but didn’t work. I’m not able to find detail documents either. Can anyone point me to the right direction?

anyone can help?

Would suggest you start at http://www.freepbx.org/support/documentation/installation and follow the links for First Steps After Installation.
