Team sizes at law offices in California

72.4% of California's law offices with employees had fewer than five people in March 2023, compared with 71.8% nationally. 86.4% had fewer than ten. At that size the phone is shared, so routing (who rings, when, and what happens after hours) matters more than the number of desk phones.

Calls a law office in California has to catch

Prospective clients often call a law office at a stressful moment and contact more than one firm, so the first firm to respond has an advantage. Attorneys are frequently in court or meetings, which makes accurate message taking and routing to the right paralegal essential. That holds for law offices in California as much as anywhere.

A few of the calls that come in to law offices in California:

Texting clients

Firms use texting for appointment reminders and document requests, keeping privileged discussion off text.

Texting from a local number in California requires carrier registration (10DLC), a one-time $49 fee on Callata.

Phone system pricing for a 7-person law office

Law offices in California average 6.5 employees, so the comparison uses a 7-person team. Priced per seat, 7 users would run $210.00 a month on RingCentral RingEX Core and $174.65 on Ooma Office Pro (month-to-month list prices, checked September 28, 2026). Callata comes to $139.00 a month for 7 users ($99 a month with 5 users included, then $20 per additional user), below both.

Over a year, that is $852 less than RingCentral for a law office in California of that size. Annual contracts lower some competitors' prices, so compare the plan you would actually sign.

How Callata works for law offices in California

For $99 a month, Callata puts a team of up to 5 on one plan ($20 for each person after that): up to 3 local numbers, unlimited inbound calls, a pooled allowance of 1,500 outbound US and Canada minutes per user, browser and cell calling, voicemail transcription with urgency triage, recorded calls with AI summaries and business-hours routing, with E911 on every number.

Porting a number you already use in California is free, and business texting is available once the carrier registration (10DLC) is approved; the registration carries a one-time $49 fee. Which specific numbers are open in a given area code depends on carrier inventory at the time you sign up.

AI agents are optional: an AI receptionist or scheduler can pick up when the team is busy or closed, take a message, send a text or email, or transfer the call. They draw on prepaid AI minutes ($0.25/minute), disclose that they are AI, and outbound AI calls require prior consent and are limited to 8am–9pm.

Firms should consider privilege and confidentiality before recording calls or using AI summaries, and follow their bar's guidance on client communications.
