iphone 7 plus echos intermittently

[MARASH43]

In the past few months my iphone 7 plus began to echo while I'm in the middle of a phone call.  It doesn't happen all the time, but seems to happen once or twice per day.  When it happens it usually lasts 15-20 seconds, then goes away.   It sounds like an old fashioned broken record, skipping and such.  Any one know how to fix this issue?   I'm on my phone a lot (for work) so this is a real issue for me.  Thanks.

Oh, my MARASH43. That certainly is not ideal to have an audio issue occur on your phone calls especially if you are using your phone for work purposes. I am happy to assist you with seeing what may be causing the issue. I sent you a Private Message so we may get started.
