Can I do 3-way calling with the LineLink device?

    Can I do 3-way calling with the LineLink device? I have the little home voip box from T-Mobile and I can receive an inbound call, press "flash" on my phone, and make another phone call. I can then flash back and forth between the two calls. I just don't know how to join the second call back to my first call to make a conference call.
