So I have a cs50 wireless headset with lifter that I want to use with my spa508g Since I want to use the lifter to answer calls, I go from the handset out to the CS50 base and then from the CS50 base to the handset. Unfortunately, this adds a weird buzzing no matter how I set the CS50. Anyone have any experieince using these with a SPA508g? Or is there a better wireless headset to use with the uc320 phones?
I have this problem too.
