Does anyone know how answer another incoming call while you are on another call from this headset, I can't seem to find out how to do this. I have even printed out the owners manual.
Probably just hit the Green send key on the phone just like without the headset.. Don't know if you can actually use a button on the headset.. but I don't have any experience with your headset
"To answer the second call, the first call must be terminated. There is no
function for placing one call on hold while answering another call from
the headset."
Actually, Sily12 is correct. I do this all the time on my 520. It works great. I have other issues with the 520 but call switching via the BB 8310 handset is not one of them.
