Read guide →How we evaluate business phone and VoIP software
VoIP platforms vary widely: some are pure cloud phone systems, others bundle video meetings, team messaging, and contact center features into one platform (UCaaS). We evaluate each tool for its stated focus rather than comparing a lightweight startup phone tool against an enterprise UCaaS suite.
Our criteria: call quality testing across different internet conditions, pricing verified from vendor sites (most VoIP tools have per-user per-month pricing with annual minimums — we flag these clearly), feature comparison against stated use cases, and G2/Capterra review analysis. We check uptime SLA claims against independent monitoring data where available.
VoIP vs traditional phone: real cost comparison for SMBs
A traditional PBX phone system typically costs $500–$2,000 per user upfront in hardware, plus ongoing maintenance contracts and per-minute PSTN charges for long-distance calls. For a 20-person office, that often means $20,000–$40,000 just to get started, before you pay a telecom bill every month. VoIP flips this to a subscription: OpenPhone is $15/user/month, Dialpad starts at $15/user/month on the Standard plan, and even RingCentral's Core plan (which includes unlimited domestic calling) comes in at $20/user/month on annual billing.
The hidden costs on the VoIP side are internet infrastructure and support. If your broadband connection is unreliable, you will need a dedicated QoS-configured router and possibly a backup connection — budget another $50–$200/month depending on your setup. Most SMBs running 10–50 users find that VoIP is meaningfully cheaper after year one, with savings of 40–60% compared to traditional phone lines, based on telecom cost benchmarks from G2 and industry surveys.
International calling is where the comparison gets more nuanced. Nextiva and RingCentral include unlimited calling to the US and Canada, but international rates vary. Dialpad's International AI plan adds unlimited calls to 70+ countries for $25/user/month — a meaningful saving for teams with frequent international calls. If you're making heavy outbound international calls, compare per-minute rates closely: some providers charge $0.02–$0.05/minute while others bundle it in the plan.
Best business phone with CRM integration
Aircall has the deepest Salesforce and HubSpot integrations of any phone system we have tested — call logs, recordings, and disposition tags sync automatically without manual entry, and you can click-to-call from inside either CRM. It starts at $30/user/month (minimum 3 users) and is purpose-built for sales teams that live in their CRM. The Pipedrive and Zoho CRM integrations are also solid, which matters for teams that are not on Salesforce or HubSpot.
Dialpad is the better choice if you want CRM integration plus AI features in one bill. Its native Salesforce connector logs call summaries and action items automatically after each call — not just call metadata. The AI Contact Center plan, which includes both CRM sync and live coaching, runs $95/agent/month. For teams where reps spend time filling in CRM notes after calls, the time savings alone often justify the price difference over a basic VoIP tool.
RingCentral connects to 300+ business tools including Salesforce, Microsoft Dynamics, and ServiceNow, making it the safest choice for larger organizations that use less common CRMs. Its Salesforce integration allows inbound screen pops, so the customer record opens automatically when a call comes in. If you are evaluating for a 50+ seat team with a complex CRM stack, RingCentral's integration breadth is hard to match — though you will pay for it at $25–$35/user/month on annual contracts.
