A business phone system has a different job to a home line: routing calls to the right person, recording for compliance, plugging into your CRM and scaling from 2 seats to 200 without a forklift upgrade. We provisioned real accounts with each provider and tested setup, call quality, admin tools and integrations.
Auto-attendants, ring groups, call queues, recording, analytics and SLAs. Consumer services (see our residential VoIP picks) skip these to hit a lower price — fine at home, limiting for a team.
Match the tier to the features you will actually use: most small teams need an auto-attendant, mobile apps and basic analytics — usually the mid tier. Check CRM integrations on the exact plan you are buying: vendors often gate them to higher tiers.
Advertised per-user prices usually require annual billing and the largest seat counts. Budget for the monthly price on your real team size, and confirm number porting is free before you commit.
Typically €10–€30 per user per month depending on tier and contract length. Advertised prices usually assume annual billing and high seat counts, so quote your real team size.
Yes — all providers here support number porting, and most port your main numbers free. Plan a small overlap period so calls are never missed during the switch.
No. Every provider works through desktop and mobile apps. Desk phones are optional and can usually be bought or rented through the provider if your team prefers handsets.
CRM screen-pop and call logging (Salesforce, HubSpot), helpdesk integrations, and calendar presence. Check your must-have integrations are included in the tier you are buying, not just the top one.
