Census published engineering firm counts for 18 metro or micropolitan areas that include part of Mississippi. The largest is Memphis, TN-MS-AR, with 108 establishments (a multi-state area; its count covers every state it spans). Single-state metro and micropolitan areas account for 80% of the statewide total; the rest are outside any published area or in areas Census suppressed.

Team sizes at engineering services firms in Mississippi

49.7% of Mississippi's engineering services firms with employees had fewer than five people in March 2023, compared with 53.1% nationally. 67.9% 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.

What a phone system costs an engineering firm in Mississippi

Engineering services firms in Mississippi average 11.6 employees, so the comparison uses a 12-person team. Per-seat business phone plans bill every one of those people. At month-to-month list prices checked September 28, 2026, 12 users on RingCentral RingEX Core cost $360.00 a month and 12 on Ooma Office Pro cost $299.40. Callata comes to $239.00 a month for 12 users ($99 a month with 5 users included, then $20 per additional user), below both.

Over a year, that is $1,452 less than RingCentral for an engineering firm in Mississippi of that size. Annual contracts lower some competitors' prices, so compare the plan you would actually sign.

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.
