3CX Deciding Factors
3CX ranks as one of our best voice-over-internet-protocol (VoIP) softphone providers with its omnichannel capabilities, such as voice, video, voicemail, live chat, WhatsApp, and Facebook integrations. This allows you to engage customers across multiple channels from a single interface. However, while it has a generous free version, it has limited software integrations compared to other providers like 8×8, Nextiva, and RingCentral.

3CX Alternatives
While 3CX is one of the leading business phone systems, it still has a few disadvantages. The wide range of 3CX phone system features may overwhelm solopreneurs or small teams with basic phone system needs. In this case, businesses with tight budgets are better off with an alternative like Grasshopper, which offers simple VoIP services. It also lacks unlimited international calling, free professionally recorded greetings, and mix-and-match plans.
Some advanced features are only accessible in higher-tiered plans, such as skills-based routing, voicemail transcription, and call recording. Alternatives, like RingCentral and Nextiva, offer similar call center capabilities starting at $30 per user monthly, but these features also make them more powerful phone systems.
If you’re looking for a 3CX alternative, here are three providers in our list of best business phone systems:

|---|---|---|---|

3CX earned a 5 out of 5 in our evaluation of its pricing. It scored top marks with its free plan, straightforward annual pricing without per-user fees, and volume-based discounts. It offers two types of plans, four hosted service options, and three self-managed solutions packages. 3CX StartUP and 3CX Free are free for up to 10 users and include team messaging, live chat, and video conferencing.
However, the 3CX pricing page isn’t as straightforward. It displays a separate annual fee for licensing and hosting for 12 users and four simultaneous calls. Although its paid plans are billed annually, 3CX offers one of the lowest per-monthly user fees on the market. Also, it has a different plan for those wanting the support and control of an on-site VoIP system.

3CX’s hosted services allow you to retain control of your phone system while remotely hosting the software from either the vendor or a third-party hosting provider. On the other hand, on-premise PBX is deployed on servers belonging to the provider and thus is managed by them entirely. 3CX works with DigitalOcean and Vultr for hosted services.
