My apologies that there is no message that comes up when calling your wife along with other contacts! I will be happy to help!
What type of phone do you have? We have heard of an issue with the Galaxy S7 doing this, and there is a software update in the works to fix it. A temporary solution for the time being is to turn off LTE/HD Voice through Settings > Mobile Data > Enhanced LTE Services.
Let us know if that works or if you have a different type of device! We will be happy to look further into it and figure out what is going on! Have a wonderful day!
