Participants on the classic Hangout web interface can see the name, phone number, and location of all voice callers, and mute them if necessary. UberConference also allows you to record the audio meeting for future reference.

See the UberConference site for more information and pricing. And check out the video to add an UberConference number to Hangouts.
