Whole Lotta Talking. Rather Tiny Bill. But How?
Grandma knows the difference between a bargain phone and a bargain phone bill. Buy equipment that suits her, then let calling providers compete for her minutes.
Updated

Doorman was made with grandmas in mind. Especially the ones who like to make every penny nickel count.
Say you give Grandma a cheap phone and a big monthly bill. That is the wrong shape of gift.
She might happily buy a nice phone once. She will find a place for it, keep the charger where it belongs, and take good care of it. What she may not want is an expensive plan to keep paying for every month, from now until forever.
We think the equipment and the monthly bill deserve separate decisions.
Buy the phone you want to keep
A Doorman system has a Brain—a regular computer running the phone software—and compatible handsets. You can start with a ready-to-use system, or use supported equipment you already own.
That equipment does useful work at home: handling calls, applying your household’s caller rules, and connecting its handsets. Choosing a different compatible calling provider does not, by itself, mean replacing the Brain and every phone in the house.
Grandma gets to choose a phone she likes holding. The person helping her set it up gets to shop for the service behind it.
Let them compete for your minutes
A VoIP provider connects your home phone system to ordinary telephone numbers over the internet. That is how Grandma can call her sister’s mobile, the pharmacy, or a friend who has never heard of Doorman.
Different providers charge differently. Some offer monthly packages; others charge for a phone number and the calls you actually make. Incoming and outgoing minutes may have different prices. Emergency calling, taxes, and other fees can add to the total.
A small per-minute rate can go a long way. For illustration, at half a cent per minute, 600 minutes costs $3 in usage. That is ten hours of talking. It is not a $3 total bill: the number, other charges, and any differently priced calls still need counting. This example is arithmetic, not a provider quote.
Our family phone cost guide walks through fuller examples, and the comparison tool lets you try your household’s calling pattern.
A better offer should be an option
When a compatible provider offers better service or better prices, you can consider switching. Your household’s phone hardware does not have to be part of that negotiation.
Keeping an existing number usually involves a transfer called a port. The new provider must confirm that it can accept the number, and someone needs to configure and test the change. Grandma should not have to learn a new routine just because someone found a better rate.
There is no prize for switching every month. A reliable provider, clear billing, and a real person who helps when something breaks can be worth paying a little more for. Let them compete for your minutes—and for the privilege of being easy to live with.
And sometimes a package wins
If Grandma spends hours on outside calls every day, a flat-rate service may be cheaper. International destinations can change the answer too. Compare the complete bill using the calls she actually makes.
A Doorman account plan is separate from the outside calling provider. Choosing Free does not make outside calls free; paid hosted services, if you choose them, belong in the budget too. Existing internet, electricity, and eventual equipment replacement also count. Outside calling depends on working internet and power, so keep another way to call for help.
The goal is a phone Grandma enjoys using, with a bill she understands and can comfortably keep paying. More “Tell me what happened next.” Less “How much is this costing me?”
