If you record phone calls for your business, or you want to record calls on your own cell, the first question is always the same: do I need the other person's permission? In the United States the answer depends on the state, and on where the other person is, not just where you are. This guide lays out the rule, the states where it is stricter, and the practical way most businesses handle it. It is not legal advice; statutes change and courts interpret them, so check the current law for your state or ask a lawyer before you rely on any of this.
The federal baseline is one-party consent
Federal law (the Wiretap Act, 18 U.S.C. § 2511) lets you record a call as long as one party to the call consents. If you are on the call, you are that party. You do not have to tell the other person.
Most states follow the same rule. In a one-party state you can record your own calls freely, and a business can record calls its own staff are on without announcing it, though most still do, for the reasons below.
States that require everyone's consent
A minority of states require the consent of all parties to a private conversation. Recording a call without the other side's agreement in one of these states can be a crime and can expose you to a civil suit. The states most consistently listed as all-party for phone calls are:
- California
- Delaware
- Florida
- Illinois
- Maryland
- Massachusetts
- Montana
- Nevada
- New Hampshire
- Pennsylvania
- Washington
A few more sit in a grey area and are safest treated as all-party:
- Connecticut requires all-party consent for civil liability on recorded phone calls, while its criminal statute is one-party.
- Michigan has an eavesdropping statute that reads as all-party, though courts have allowed a participant in the conversation to record it.
- Oregon requires all-party consent for in-person conversations and one-party for phone calls.
If you only remember one thing: California, Florida, Illinois, Pennsylvania, Washington, Maryland and Massachusetts are big states with strict rules, and a lot of calls touch them.
What counts as consent
Consent does not have to be a signed form. In practice it is established one of two ways:
- An announcement at the start of the call. "This call is being recorded" or "may be recorded for quality and training". If the other person hears it and keeps talking, they have consented. This is why nearly every company you phone plays that line.
- Express agreement. Asking "Do you mind if I record this?" and getting a yes. Record the yes.
Beeps every 15 seconds were an older method and are rarely used now; the announcement is the standard.
When the two people are in different states
Here is where businesses get caught. If you are in Texas (one-party) and you call a customer in California (all-party), which law applies? Courts have gone both ways, and California courts in particular have applied California law to out-of-state callers recording Californians.
The safe rule, and the one almost every call centre and phone system uses, is: follow the strictest state that could be on the line, which means all-party, which means announce it. A recording notice costs you two seconds per call and removes the question entirely.
What this means for a business phone system
If your phone system records calls, it should be able to play a recording announcement, and you should turn it on. A few more points worth checking:
- Inbound and outbound both. A greeting on inbound calls covers callers who phone you. For outbound calls the rep, or the system, needs to say it.
- Staff consent too. Employees are parties to the call. Written acknowledgement in an employment policy that calls are recorded is normal.
- Transfers and conferences. If a third person is added to a recorded call, they need to hear the notice as well.
- Health information. If calls can include patient details, recording adds a HIPAA dimension on top of consent: the recordings are protected health information, and the vendor storing them needs to sign a business associate agreement.
Quill Hound Voice records calls with a recording announcement you control, and Quill Calls records and transcribes tracked marketing calls the same way.
Recording calls on your own cell phone
Personal call recording is harder than it should be, because Android and iPhone block apps from recording ordinary cellular calls. The apps that do work carry the call for you over their own line, and the good ones handle consent the same way a business does: by playing a short notice so the other person always knows. That is how Talk Current works, and why it keeps your own number showing to the people you call.
Quick answers
Is it legal to record a phone call without telling the other person?
In most states, yes, if you are a party to the call. In the all-party states listed above, no. If either person might be in an all-party state, announce it.
Does "this call may be recorded" count as consent?
Yes. If the other person hears the notice and continues the call, that is treated as consent in all-party states. Make sure it plays before any substantive conversation.
Can I record a call I am not part of?
No. Recording a call between other people without the consent of at least one of them is wiretapping under federal law and illegal in every state.
Do the same rules apply to video calls and voicemail?
Video calls are treated like phone calls: the conversation is private and the same consent rules apply. A voicemail is a message the caller knowingly left for you, so keeping it is not recording a conversation.
What about text transcripts made by AI?
A transcript is derived from a recording, so the consent rules for the recording govern it. Treat transcripts with the same care as the audio, especially when they can contain health, financial or identity details.
