Is there a conference call/speaker phone made that is supported by iPhone?
Is there a 'conference call accessory available for iPhone that will provide good sound, in and out, in a small conference room?
I've not tried it yet, but some of my colleagues swear by the Jambox (by Jawbone) as something that works not only as a speaker but also as a speakerphone. It connects via bluetooth.
I'll probably borrow one for my next call and see if it works as well as they claim ;-)
