Any way to amplify a call?

Hello,
Is it possible to amplify the voice in call communication? some times the caller has a very weak voice and I need to hear him out.

Thank you

Aside from increasing the volume, you can try to see if some Accessibilty options might help in some way, like enabling/disabling noise cancellation and some other similar sound options. Also using a headset might help as well.
