reoccuring sound that happens right after I hang up from a phone call.

[darcisuttle]

I get a recurring sound that happens right after I hang up from a phone call. It is not indicating a new voicemail, email or text or telling me there is a call coming in. It makes a few computer like noises right after I hang up from a call. It took me a couple weeks to correlate that is when it was happening. I have called my phone from home, my daughters, my dads and work and I get the sound on all of these right after I hang up the call when I hang up.
