PhoneBridge basics

Hi - I have a few newbie questions about PhoneBridge.
  1. Is a headset required with our IP phones?  If not, how would placing and receiving calls work with a handset?
  2. Will this work with a ring group?  Our office shares a main number.
  3. Any plans to integrate with 8x8 or FortiCall/FortiVoice?
