Pretty good – Speek - Free Conference Call, Online Meetings, Business Communication, Teleconference, Group Calls, International Three-Way Calling, Phone Audio Bridge for mobile teleconferencing, Collaboration Review

Needs ability to join someone else's call to a number not your mobile. Like if you're in a conference room. "Drop Caller" failed me at a very important moment. Didn't work at all.
