I cannot find a definitive answer ..
Promo video everywhere .. and on Youtube as 'bluetoothworld ice device'
There are buttuns on each side .. but I think that one large blob on the front may well be the button for incoming calls/hang up.
I'm sure you wouldn't use the remote to answer. I think the telephone icon on remote is to select plugged in file browser in the attached phone.
You could try sending an email to their support ..
