Your Phone Number Is Rented, and So Is Your Call History

The number printed on your signage is often registered to a vendor. Even when the number ports cleanly, three years of recordings and call history usually do not travel with it.

There is a number on the back of your vehicles. It is on the awning, on the brochures, in four hundred directory listings, on a magnet on a thousand refrigerators, and in the phone of every patient who has ever called you.

Find out who it is registered to. There is a real chance the answer is a company you pay monthly.

The number on your car wrap

Tracking numbers made this normal. Somewhere along the way a vendor provisioned a number so calls could be attributed to a campaign, that number performed well, and over several years it migrated onto the signage, the listings and the business cards. Nobody chose it as the practice's main line. It became the main line by accumulation.

Numbers provisioned that way are typically held in the vendor's account, with the vendor as the customer of record at the underlying carrier. Your practice is a user on an account, not the subscriber of a number.

A number you cannot port is not a marketing asset. It is a switching cost your vendor is holding on your behalf.

Subscriber of record

Porting a number is a regulated process and it runs on a specific fact: who the carrier believes the subscriber is. The request has to come from that party, matched against the billing name and service address on file. If the vendor is the subscriber, your port request is a request for a favor, not an instruction.

Most vendors cooperate. The ones that do not tend to discover a reason for delay at exactly the moment you give notice, and by then you have nothing left to hold back, because every day the port is stalled is a day your signage points at a number somebody else controls.

Check it now, while nobody is leaving. Ask your current provider for the customer service record for each number you advertise. The name on it is the answer.

Porting is paperwork, not a favor

Three practical notes, learned the hard way on a migration of our own.

A number in active use at a vendor who is also your website host and your CRM is three dependencies wearing one invoice. Separating them takes planning rather than a weekend.

Ported numbers go quiet for a window, usually minutes, occasionally hours. That window is survivable if you choose it and catastrophic if a vendor chooses it for you on a Tuesday in your busiest month.

Directory listings do not follow a port. Your listing, your maps profile, your directories and every citation built over nine years each hold a literal string of digits, and if you change the number rather than porting it, somebody has to update all of them by hand.

The part nobody asks about

Here is the question that gets skipped in every vendor change, and it is the one that costs the most.

When you leave, do you get the recordings?

A call log is not call history. Most exports hand over a spreadsheet of dates, numbers and durations, which is enough to count calls and useless for everything else. The recordings and transcripts are the asset: they are how you know which inquiries were qualified, how your front desk actually answers, what patients ask before they book, and which campaign produced a conversation worth having.

Three years of that is a dataset you paid for one call at a time. In most contracts it is also the vendor's property, deleted on a retention schedule you have never read.

And there is a second problem stacked on the first. Those recordings are patient conversations, so whoever holds them is handling protected information on your behalf. If you cannot get them out, you also cannot say where they are, which puts you back in the problem described in our post on the vendor chain.

Three questions for your current vendor

  • Which legal entity is the subscriber of record for each number we advertise? Send the customer service record.
  • If we give notice today, what is the port process, what does it cost, and how long does the line go quiet?
  • What exactly is in the export: call log only, or recordings and transcripts, and in what format?

Put all three in one email. A vendor who answers all three in writing within a week is a vendor you can safely stay with.

Why this is not a solved problem

When we surveyed the systems serving practices in this specialty, voice was the clearest void in the category. Plenty of platforms integrate with a phone vendor. Very few treat the phone as part of the practice's own record, which is why so many practices end up renting the single most visible asset they own.

It matters beyond the switching cost. Phone calls are where cash-pay elective patients actually convert, so a phone system that lives outside your records is also a hole in your measurement. The call that produced a consultation cannot be connected to the advertisement that produced the call if the call data belongs to somebody else.

Our position

The practice is the subscriber. The recordings and transcripts are part of the practice's export, in a usable format, without a negotiation. If a practice leaves us, the number goes with them, because a product that keeps customers by holding their phone number has stopped being a product.

That is not generosity. It is the only arrangement that survives the question any owner should ask a vendor before signing: what do I walk out with?

Notes

Porting rights and the customer service record process are governed by federal number portability rules. The underlying obligation is on carriers, which is why the identity of the subscriber of record, rather than who pays the invoice, determines who can authorize a port. Retention periods for call recordings are set by contract and vary widely, so read the agreement rather than assuming a default.

Your patients. Your data. Your number.

Native voice, call history and recordings that belong to the practice, in the same system as the records and the reporting. Not a line item on somebody else's account.
