Does the OBi support three-way conferencing?
Yes. The OBi supports three-way conferencing. Whilst in a two way call, to add a third, just press the flash button or the 'hook' on the phone. This will place the other side on hold and allow you to dial the party to be conferenced. When you hear a dial tone, dial the party to be conferenced. When they answer, at any time, press the flash button or hook again and all three parties will be in a conference call.
