Sumo LM340 and iphone pairing

Hi,

Has anyone got an LM340 that you’ve managed to pair to an iPhone 7?

I’ve got the zumo to pair to my headset and I can see the iPhone but each time I pair the zumo states “this isn’t a headset”

So I have checked and it’s the latest updates on the zumo.

Be good to be able to see who’s calling on the zumo and allow me to answer or reject the call.

Oh I did try unpairing the IPhone from the headset no difference zumo still not happy.

Thanks
Mark
