Go to dialer>settings>call>call alerts and unchecked the call connect or call end tone.

It's unchecked and it still happens.
Well Duh! Turns out, Signal Check was alerting me of network status changes after phone calls ended. My phone was in my pocket while I was in the boonies and it kept alerting as it went in and out of service.
The answers were helpful though as the call end notification was on even before I found the Signal Check setting. Appreciate the answers!
