When im on my phone it sounds distorted when i talk to business associate's

A myriad of things that could be happening here, from a bad signal to a poor WiFi connection if you're using WiFi Calling. Does it happen with certain businesses all the time, is it sporadic, is it random? Have you checked your mobile signal when making a call? Does it happen when placing the call or also when receiving? Have you checked with your carrier in case there's something going on with your line settings?
