54.0% of Louisiana's engineering services firms with employees had fewer than five people in March 2023, compared with 53.1% nationally. 68.1% 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.

Phone system pricing for an 18-person engineering firm

Engineering services firms in Louisiana average 17.8 employees, so the comparison uses an 18-person team. Priced per seat, 18 users would run $540.00 a month on RingCentral RingEX Core and $449.10 on Ooma Office Pro (month-to-month list prices, checked September 28, 2026). Callata comes to $359.00 a month for 18 users ($99 a month with 5 users included, then $20 per additional user), below both.
