There is no single best phone system, so rank options by seats, work style, and current cost.
Separate desk workers from people who move, because that split changes the shortlist.
Use the all-in number on your current bill as the baseline.
Each range below is the published premium price, widened by that vendor's confidence band. State tax is not included, because it depends on where you are. Prices as published by each provider. Data as of 2026-10-04.
A TechEstimate is a range. A written proposal is the number you can hold a provider to.
These phone systems are alphabetical. This is not a quality ranking.
TechlyScore ranks them for your setup when you compare in real time.
123NET: $21 to $39 per user/month. 8x8: $26 to $30 per user/month. Aircall: $35 to $45 per user/month. AireSpring: $24 to $46 per user/month. Allworx (Windstream): $18 to $32 per user/month. AT&T Office@Hand: $26 to $34 per user/month. Avaya Cloud Office: $22 to $28 per user/month. BCM One: $19 to $35 per user/month.
More providers are in the same table. The list stays alphabetical.
The first invoice can add fees that the ad price skipped.
Ask for the all-in total. If they will not say it, that is the answer.
Upload your bill if you have one. Or adjust your sliders if you are starting fresh.
You could pay less. You could also pay about the same and save the research time.
The next step on this page is to compare in real time.
There is no single best system. The right one depends on how many people need a phone, whether they sit at desks or move around, and what you pay now. Rank them against your own setup rather than a national list.
They are usually the same thing. VoIP is the technology that carries the call over the internet. Cloud describes where the system runs. A cloud phone system is almost always VoIP.
If nobody needs a desk phone, a virtual system that rings laptops and mobiles is usually enough. Look at how many numbers you need and whether texting is included. Those two things separate most of the options.
Most do not. A copper line is still useful for an alarm panel, a lift, or a card terminal that will not run over the internet. For voice calls, a landline is rarely the cheaper or better option now.
At a minimum: calls on desk and mobile, voicemail, a main number that rings the right person, and call transfer. Texting and call recording are common next steps. Anything beyond that should answer a problem you actually have.
