Moving from a copper landline to VoIP: what happens to your number and your blocking
Illustrative example. The household below is invented, a composite of situations that come up when people move a home phone from copper to the internet. No real person, provider or company is described, and the details are there to show how the steps fit together.
The decision
Ruth had the same copper landline for longer than her son Daniel had been alive. The number was printed in her address book, taped inside the kitchen cupboard, and stored in the contacts of her doctor, her bank and her granddaughter's school. Then a letter arrived: the old copper service on her street would be retired in the spring, and a home phone over the internet, offered by a cable company, would cost less. Daniel, who lived two towns away, said he would help. Ruth said she would rather keep the phone, and what she meant was that she wanted to keep everything the phone did.
The first thing Daniel did was nothing, which is the part people skip. He did not cancel anything. He asked the new provider two questions on the phone: would Ruth's number move over, and what did the plan include for blocking calls. The answer to the first was usually yes, through number porting handled by the new provider, once the provider had checked that it covered her address. The answer to the second was a list: a web dashboard with a block list, quiet hours and a call log, plus a spam filter that labeled suspected calls. The labels, the representative admitted when Daniel asked, were estimates.
Then he took an afternoon, a notebook and a pot of tea to Ruth's kitchen table, and wrote things down. It was dull work, and it turned out to be the most valuable part of the whole move.
From her old account page he copied a block list of eleven numbers. He asked which star-code features she used and how she turned them on; she had anonymous call rejection switched on and had forgotten it was there, which explained why the phone had been so quiet in the evenings. They listened through her saved voicemails and kept two, one from her sister and one from a hospital. Last, he asked about the pendant she wore around her neck, a medical alert device that dialed out over the phone line when she pressed the button.
That last conversation changed the plan. Daniel called the device maker, not the cable company, and asked whether her model worked over an internet phone. In this story the answer was that the model had been built for copper lines and might not work reliably on the new service, and the maker suggested another arrangement. They sorted that out before the switch, not after a fall. Many such alarms and alert devices were designed for copper, and the conversation is worth having even if you decide against every other precaution.
The week of the switch
The port took a few days. The provider asked for her old account number and a PIN that proved the account was hers, then handled the request itself. Daniel had warned Ruth that the number might go quiet for a short while during the transfer, so she was not alarmed when it did for an afternoon. He had also not let her cancel the old line until the new one had been tested and the number had actually moved. That ordering mattered. Had the port stalled, she would still have had a working phone.
There was one more thing about the new service that Daniel raised, mostly because it nagged at him: the power. Copper lines often keep working when the lights go out, and the line carries its own small current. An internet phone depends on the modem having power. Ruth lived alone and the phone was her lifeline, so a battery backup for the modem was a necessary purchase, not an extra. They bought one.
On the first morning with the new service, before anything else, Daniel logged in to the dashboard and switched on every feature the plan included. He rebuilt the block list from his notebook. He turned anonymous call rejection back on, since the old setting had stayed behind with the old carrier, as features kept in a carrier's network normally do. Her cordless phone had its own block list, and that one came along intact, because lists kept in your own devices stay with the hardware. He checked that the handset worked with the adapter, and it did. The voicemail greeting and the old messages did not move, which is why they had saved the two that mattered. He recorded a plain new greeting that gave away nothing.
Then he ran the three calls that show in five minutes whether a move kept the protection or lost it. A friend rang with a hidden number, which should have been rejected. A second call came from one of the eleven blocked numbers, and a third left a voicemail. The second and third behaved. The first one rang through. The anonymous-call-rejection switch in the dashboard had not saved, and the setting was off. Daniel turned it on, tested again, and this time the friend heard the rejection recording. Without the test, Ruth would have lived with an unprotected phone for months while believing the opposite.
The day the port finished, Daniel was not in the room, which was part of the plan. Ruth had a card by the phone in his handwriting with five lines on it: the new provider's customer service number, the date the old line would be closed, the three test calls, and the word "wait." The last one was for herself. If the phone seemed odd in the first hour, she was not to cancel, switch or press anything until he rang her on her mobile that evening. It was a small piece of paper and it prevented a long afternoon of improvising. People in the middle of a move tend to fix a problem that does not exist, and in doing so they create one that does.
The first month
The dashboard had one pleasant surprise. It kept a log of every call that rang, and in the first week Ruth noticed that the call at four every afternoon was the same number each time. She added it to the list herself, in about ten seconds, which she could never have done with a star code.
Daniel also made a list of people to tell. Banks, pharmacies, doctors and schools often keep a home number on file for urgent contacts, and some use it for verification. Because the number was staying, nothing changed for them, but they confirmed her details after the port, since a briefly disconnected number can miss an important call. They kept copies of the final bill from the old provider and the confirmation of the port from the new one. If a charge looked wrong a month later, those two pieces of paper would save a long phone call.
Over the next weeks Ruth watched the first bill for charges that should have stopped, and wrote down any call that behaved oddly. When a friend said she had once heard a busy signal, Ruth told the provider early, because early reports are easier to trace than complaints made three weeks later.
One branch of the story did not happen but could have. Had the number not been able to move, Ruth would have taken a new one. A new number may be quieter at first, but it can arrive with calls meant for its previous owner and it gathers marketing calls over time. In that case Daniel would have registered it with the Do Not Call Registry, told the people who matter, and asked the old provider to keep the old number alive briefly with a message pointing to the new one.
Ruth, for her part, kept the two voicemails Daniel had saved and played one of them a few weeks later, on a Sunday, when she wanted to hear her sister's voice. Nobody had planned for that use, and nobody could have, but the afternoon with the notebook had made room for it. The move had taken one afternoon of preparation, a few days of waiting and a small card by the phone. Of the three, the card was the cheapest and the most used.
What to take from it
The order of events is the lesson. Check coverage and ask about porting before anything is cancelled, and keep the old line until the new one has been tested. Write down your block list and your star-code settings first, because features kept in the old carrier's network usually do not follow the number, while settings kept in your own handset or plug-in blocker stay with the hardware. Ask the alarm or medical-alert maker before the switch whether the device works on an internet phone. Decide about a battery backup. Turn on everything the new plan offers in the first week, and run the three test calls, because that is what turns a hopeful guess into knowledge.
If you want the wider comparison of the two kinds of line, landline versus VoIP sets out what changes. For wording to use with the new provider, see how to ask your phone company about robocall protection. If names look odd for a while after the move, that is normal, and the myths about caller ID names explains why: name databases update slowly, so a ported or recycled number may show an old name for some time. And the glossary of landline blocking terms will help you read the dashboard when you meet it.
