Intermittent issue - Callers can't hear us

Frequently, but inconsistently, our Business Voice service will go through a phase where many incoming calls will be received where we cannot hear the person on the other side of the call, though they have reported that they can hear us. Once in a while this extends to outgoing calls we make as well. This has happened many times since we moved our office to a new location back in December 2021, though the issue hasn't really come up before a few months ago. We never had issues at the old location, though we have encountered some issues with our Comcast Business account since we moved as the account was initially set up incorrectly (mostly resolved now). I've also noticed that our call history doesn't show up in the call history section of the Business Voice Dashboard through our account online, and wonder if the two stem from the same root issue.
