Why does my Droid Turbo 2 answer when my Vonage phone rings?

Question

My Vonage (VIOP) phone is connected to my wireless router. When one of the wireless phones connected to that router rings, my Droid Turbo 2 also rings and I can answer on either. My Droid is connected to my wireless router wifi at home to save on data. Vonage has call forwarding turned off. Is there a way to stop this cross talk ringing?

Yes I do have the Vonage extension app installed. I think I found a setting that will fix that under incoming calls. Thanks a lot. I am new to smart phones, so some things do not occur to me.
