microphone system

We have a Polycom system with 2 separate wired microphones but our people that call in still have issues hearing between people talking and the wired mics picking up keyboard typing etc. Anyone used any other sort of wired system connected to a computer or any other solution for this? Our out of town users enjoyed using zoom calls more but now that most of us are in a single room it has become an issue for those not in attendance at the meetings. Any ideas or suggestions appreciated.
