Law firm phone system: what a small firm needs.
What makes a law firm phone system different?
A law firm phone system has to do what any business phone does, plus four things most do not: record calls within your state's consent law, keep client texts out of personal phones, file every call to the right matter, and keep privileged conversations under the firm's control. Everything else is features.
Seven things a law firm phone system should do
Use this as the checklist when you compare systems, including ours.
Staff answer from a desk or their own phone, without giving out a personal number
An app on the computer and on each phone, calling and texting from the firm's number. When someone leaves, their client conversations stay with the firm.
Recording that follows the law where you practice
Some states let one person on the call consent to a recording. Others require everyone's consent. Your system should let you turn recording on or off by line, and announce it where the law requires it.
Texting that is tied to the case and properly registered
Clients text. Those texts belong in the file, not on a paralegal's personal phone. Business texting from a local number also has to be registered with the carriers, or messages quietly stop being delivered.
Every call written down, and filed where it belongs
A transcript with who said what, and a note saved to the right matter. Billable phone time should be easy to log, because it usually is not.
The right person rings, day and night
Business hours, lunch, after hours and holidays each route differently. New leads should reach someone who can take them, not a voicemail box.
911 works from every line
Federal rules require multi-line business phone systems installed since 2020 to let anyone dial 911 directly, without a prefix, send a location emergency services can use, and alert someone at the firm. Test it.
You keep your number
Your main number is on every letterhead and every Google listing. Moving it to a new system should be planned, and the old service should not be cancelled until the move is done.
Recording calls: know your state
Most states are one-party consent: anyone on the call can agree to record it. A smaller group requires every party to agree, including Massachusetts, Pennsylvania, Florida, California and Maryland. New Jersey, New York and Indiana are one-party states. Justia keeps a 50-state survey worth checking for yours.
The practical rule for a firm: know which calls cross state lines, announce recording where the stricter rule applies, and make sure the system lets you turn recording on or off by line instead of for everyone at once.
The phone system we build
We build complete phone systems for law firms. Ours runs as a law firm's main line today, on the number the firm already had. It includes:
- Calling and texting from the desktop and from staff phones, on the firm's number.
- Recordings and transcripts with speaker labels, searchable later.
- Call notes filed to the matter, and texting tied to the case instead of someone's personal phone.
- A finished call can become a time entry in Clio, with the description ready to edit.
- Caller ID that shows who the client is before anyone picks up.
The full story, including moving the firm's real main number, is in the law firm phone system case study.
Common questions
What is the best phone system for a small law firm?
The one that keeps client conversations with the firm instead of on personal phones, records within the law of your state, files calls and texts to the right matter, and works from a desk and a phone. Price matters less than whether your staff will actually use it.
Can a law firm record client calls?
Often, but it depends on the state. Massachusetts, Pennsylvania, Florida, California and Maryland are among the states that require everyone on the call to consent. New Jersey, New York and Indiana require only one party. When a call crosses state lines, many firms follow the stricter rule. Check your state's law and your bar's guidance.
Can we text clients from the office number?
Yes, once the number is registered for business texting with the carriers. Keep those texts in a system the firm controls, so they are part of the record and do not leave with an employee.
Can we keep our current phone number?
Almost always. Moving a number between carriers is routine, but the carriers control the timing, so plan it and do not cancel the old service until the move is confirmed.
Should we use an answering service instead?
If the only problem is that nobody picks up after hours, an answering service or an AI receptionist may be all you need. A phone system is the bigger decision: it is how the whole firm calls, texts and keeps records.
