Phone system pricing for a 17-person engineering firm

Engineering services firms in Colorado average 17.2 employees, so the comparison uses a 17-person team. On a per-user plan that headcount sets the bill: $424.15 a month on Ooma Office Pro or $510.00 on RingCentral RingEX Core at list price (checked September 28, 2026). Callata comes to $339.00 a month for 17 users ($99 a month with 5 users included, then $20 per additional user), below both.

Over a year, that is $2,052 less than RingCentral for an engineering firm in Colorado of that size. Annual contracts lower some competitors' prices, so compare the plan you would actually sign.

Area codes in Colorado

Colorado has 6 geographic area codes in service according to NANPA. Callata includes up to 3 local numbers, so an engineering firm can hold a number in more than one of them.

How Callata works for engineering services firms in Colorado

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 Colorado 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.
