Team sizes at law offices in Massachusetts

72.8% of Massachusetts's law offices with employees had fewer than five people in March 2023, compared with 71.8% nationally. 87.7% 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.

Why the phone matters for law offices in Massachusetts

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 Massachusetts as much as anywhere.

Typical inbound and outbound calls for law offices in Massachusetts:

Texting clients

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

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

Phone system pricing for a 7-person law office

Law offices in Massachusetts average 7.3 employees, so the comparison uses a 7-person team.

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 Massachusetts of that size. Annual contracts lower some competitors' prices, so compare the plan you would actually sign.
