Voip client to use the phone number inside the home router, can something like this even exist?
What I'd like to do is to go around with a small 4g router that i can cut power to in order to have more privacy but still the convenience to use a lan wherever i need one, not having a sim in my personal phone, but still be able to make calls on the go. I'd also like to use my home network's phone number, that we may call the household number, just with an app. Is this even possible? Is it possible to receive also sms on a similar client?
