I need to be able to use anytime - and anywhere! - three mobile phones with a single bluetooth headset. Mobiles and headset supports A2DP and HFP bluetooth v2.0 profiles. I do not need to simultaneously use all at once but certainly I don't want to disconnect one in order to pair another.
According to the manual of the headset I'm using, it is able to make multipoint connection with only two devices. I have confirmed the manual specs as the headset ignores pairing requests from a third device while already paired with two.
I would prefer to keep the current headset if possible, as I'm quite confortable with it.
I tried searching for a portable intermediate device that would act as a proxy (ie. that device would A2DP/HFP pair a decently large number of phones, tablets, fm tuners, tv sets, pc - on one side -, then pair with the headset on the other side, so phones will all think they have paired with the headset proxy while the headset will think it's paired to ONE device) but I'm out of ideas of search keywords before finding any!
