I've got a yealink t46g that works fine on my 3cx setup but using it with plantronics cs510 headphones is a disaster. The incoming sound becomes over processed with some cut outs. I tried using an old cs361n headset and that was much better. Any advice for tweaking settings in 3cx or the t46g to improve the cs510 sound? (I already tried toggling the cs510 to 'wideband' and if anything that was worse.) Is there something I should be doing with the codecs? Any other suggestions? I've been assuming that the cs510 quality should be better than the cs361n quality but maybe not?
