Each business phone system provider gets a 0–100 IFR Score from nine published factors, led by reputation (25%), review volume (15%), service focus (15%) and recency (10%). An IT firm with no Google reviews scores zero on rating, review volume and recency; other factors we cannot measure are left out.

Do business phone system providers outside North Tustin count in this ranking?
Yes, if they are within 50 mi of the North Tustin city center, our service radius for business phone system providers. Each listing shows where the IT firm is based and how far away it is. Proximity is 5% of the IFR Score, so a nearby IT firm gets a small edge.
Can business phone system providers pay to rank higher on ITFirmsRanked?
No. The IFR Score never reads payment status, and this ranking has 0 paid placements. Up to 3 Featured IT firms may appear above the list, labelled Sponsored and showing their honest rank.
What does a business phone system provider do?
Business phone system providers set up and support office phone systems, mostly cloud VoIP today: numbers, desk phones, call routing, voicemail and contact-centre features.
How are business phone system providers in North Tustin ranked?
By IFR Score: Google rating and review volume, recent reviews, opening hours, how clearly the firm does business phone systems and VoIP, distance, a claimed profile, our badge and verified client reviews. Sponsored placements never change the order.
Can we keep our phone numbers if we switch providers?
In most cases yes: numbers can be ported to a new provider in the US and Canada. Keep your current service active until the port is complete, and ask the new provider to manage the port request.
What about 911 calls on a VoIP system?
Each phone needs a registered location so 911 calls go to the right place. In the US, multi-line systems must support direct 911 dialling and send dispatchable location information under federal rules (Kari’s Law and RAY BAUM’S Act). Ask the provider how they set this up.
