When a company starts looking for a replacement for its phone system, Sangoma and 3CX often appear on the same shortlist. Both target businesses replacing aging phone systems. Both handle voice, video, and messaging. Both appear in the same search results. On a feature checklist, they seem like close competitors.
They are not. The two platforms fundamentally ask different things of the customer, and that difference determines which one is the right fit.
3CX is a software-based IP PBX. The customer or a channel partner hosts, configures, scales, and maintains it. Sangoma is a fully managed business communications platform business communications platform with cloud, hybrid, or on-premises deployment options, built and operated on its own infrastructure.
One company hands the customer a toolkit. The other hands them a working phone system.
Purchasing discussions between the two phone system providers come down to three specific points: 3CX’s concurrent billing model (concurrent calls, not seats), customer-managed responsibilities across all 3CX deployment types, and a cost stack—hosting fees, SSL certificates, $75 support tickets—that is not obvious from the license price. The sections below detail each of them.
Sangoma vs 3CX: Key Differences at a Glance
The table below covers the main decision factors. Each row is a short, factual statement. 3CX has real strengths worth recognizing: deployment flexibility across self-hosted, partner-hosted, and cloud-hosted configurations; support for video conferencing with up to 300 participants; and an advanced PBX feature set suited to SMBs that want precise call control. The full table follows in each section below.

Pricing models that don't compare apples to apples
Both enterprise communications platforms use fundamentally different billing structures, and the difference matters most when a business starts to grow or handle higher call volumes.
How 3CX pricing works
3CX licenses by simultaneous calls (SC): the number of calls that can be in progress at any given time. For businesses with low, predictable call volumes, this can seem economical. The practical problem arises for multi-site businesses and any team with variable call patterns, where peak concurrency is difficult to predict. Users have reported unexpected reductions in free license channels, which can lead to unplanned upgrade costs during the contract.
Beyond the license itself, 3CX deployments involve several additional cost layers. The SIP trunk is sourced and managed separately. Hosting costs $250 to $2,000 annually depending on the configuration. SSL certificates are an additional expense. Support is billed per ticket at $75 each, which means troubleshooting costs scale with the number of issues encountered.
How Sangoma pricing works
Sangoma charges per seat. Each user pays the same price, regardless of call volume, and that price includes 24/7 support, voice, video, messaging, and team collaboration. Switchvox Cloud seats include a Sangoma P325 desk phone. No additional hosting fees, no SSL fees, no per-ticket support fees.
One point buyers often overlook: even 3CX's hosted option requires customers to source, configure, and manage their own SIP trunks. “Hosted” in the 3CX model does not mean fully managed.
| Cost factor | Sangoma | 3CX |
|---|---|---|
| Pricing model | Per seat | Per simultaneous call |
| Cost predictability per user | Fixed; same price regardless of volume | Variable; tied to peak concurrency |
| Support cost | Included 24/7 | $75 per ticket |
| SIP trunk cost | Not required with cloud; on-premises Switchvox requires a separate SIP trunk, available through SIPStation | Sourced by the customer, additional cost |
| Hosting cost | Included in cloud plans | $250–2,000 annually |
| SSL / security | Included | Additional fee |
| Hardware / configuration cost | P325 included with Switchvox Cloud seats | On-site technician; labor often > $500 per phone |
Deployment flexibility for different operational needs
Both communications platform providers offer several deployment paths. The difference lies in how much work falls to the customer.
3CX's three options (3CX-hosted, self-hosted on AWS or Azure, and partner-hosted) leave configuration, scaling, and maintenance largely to the customer or their channel partner. The self-hosted option on public cloud platforms requires in-house IT expertise. Multi-site deployments require license recalculation and reconfiguration for each site.
Sangoma’s cloud and hybrid deployments are managed end to end, including updates, scalability, and call routing. Switchvox Cloud runs on Sangoma’s own infrastructure with no on-site hardware requirements. The same software (Switchvox) runs on-site and on a virtual machine, which means moving from one deployment model to another does not require relearning the platform.
3CX suits teams with strong in-house IT capabilities or a trusted reseller relationship ready to take on configuration work. Sangoma suits operations teams that want communications to work without a dedicated PBX administrator.
| Deployment option | Sangoma | 3CX |
|---|---|---|
| Cloud hosting | Fully managed by Sangoma 24/7 | Customer manages SIP trunks and configuration |
| Self-hosted (AWS, Azure) | Supported | Requires significant in-house IT expertise |
| On-site | Supported | Managed end to end by the customer |
| Hybrid (cloud + on-site) | Yes, with local survivability options | No native option |
| Multi-site deployment | Rapid provisioning via the online partner portal | Requires a license recalculation per site |
| Migration between deployment types | Same software on-site, VM, and cloud with a minimal learning curve | Different configurations by deployment type |
What it takes to keep each platform running
Once a phone system is online, the ongoing maintenance burden is often where the true cost of ownership emerges.
3CX customers manage system updates, scalability, and some maintenance tasks themselves unless a partner has taken on this work. SIP trunk management falls to the customer in all deployment configurations. 3CX users have reported unexpected feature deactivations in new platform releases, including smartphone push notifications and sudden reductions in free license channels. For businesses that rely on a specific feature every day, this kind of unpredictability creates real operational risk.
Sangoma manages all of this for the customer: updates, scalability, call routing, and security patches, all on its own private network. The operating model is designed for teams without a dedicated PBX administrator.
| Responsibility | Sangoma | 3CX |
|---|---|---|
| System updates | Managed by Sangoma | Managed by the customer or partner |
| Scalability and capacity | Managed by Sangoma | Requires a license recalculation |
| SIP trunk configuration and management | Included (SIPStation) or managed | Sourced and managed by the customer |
| Call routing and configuration | Managed by Sangoma | Managed by the customer or partner |
| Security patches | Managed by Sangoma | Managed by the customer |
Hardware ecosystem: one vendor vs multiple vendors
3CX deployments typically require third-party hardware at several points: SBCs for IP phone communication with hosted 3CX, external SIP trunk providers, and separately sourced desk phones. Each component adds a vendor relationship, a separate support contact, and a potential point of failure.
Sangoma manufactures its own phones, SBCs, and gateways. Firmware, feature support, and troubleshooting go through one vendor. IT teams manage fewer procurement decisions, fewer compatibility issues, and one support contact instead of several.
| Hardware component | Sangoma | 3CX |
|---|---|---|
| Desk phones | Sangoma P-Series (P325 included with Switchvox Cloud) | Third-party only |
| SBC | Sangoma integrated SBC | Third-party SBC required |
| Gateways | Sangoma in-house | Third-party |
| SIP trunk | Integrated SIPStation (auto-configured for on-site) | Sourced separately by the customer |
| Legacy device support | ATA compatibility, third-party phone integration | Limited |
| Phone branding | Customizable with company logo | Not available |
| Vendor relationships to manage | One | Several |
Network compliance and security
Sangoma’s cloud infrastructure runs on a PCI-certified, HIPAA-compliant private network with built-in redundancy and a 99.999 % uptime guarantee. Industries with regulated data requirements, including healthcare, retail and manufacturing, benefit from this compliance posture integrated into the platform rather than from separate configuration and maintenance.
3CX customers who self-host on AWS, Azure or on premises are responsible for their own security stack, patch cadence and compliance configuration. The platform does not provide compliant infrastructure by default; that work falls to the customer or their partner.
Feature sets and user experience
Sangoma offers a complete communications suite: voice, video, messaging and collaboration, with every seat at no additional license cost. Switchvox Cloud goes further with an integrated departmental contact center. Users get the tools they need from day one without tier escalations.
The standard 3CX plan is limited in features. Most useful capabilities require an upgrade to the Pro or Enterprise tiers, adding cost and complexity to an already tiered pricing structure.
In terms of user experience, the 3CX administration interface reflects its origins as a traditional PBX and is less intuitive than modern UCaaS platforms. Sangoma is designed so that non-experts can deploy and configure it without dedicated IT resources.
Support quality
3CX support packages are sold separately and billed per ticket at $75 per case. Support is not included in the license. Sangoma includes 24/7 support with every seat at no additional cost, backed by dedicated platform engineers and high-quality onboarding.
The results are reflected in the numbers. Over a measurement period, Sangoma’s support team raised CSAT from 73.8 % to 94.6 %+ and added nearly 29 points to NPS, improvements attributed to the company-wide “One Sangoma” customer experience initiative. Partners and customers describe the team as a “safe pair of hands” when reliability is critical. Full details are available in Sangoma’s customer experience case study.
Sangoma also maintains a strong on-premises roadmap, backed by dedicated platform engineers—a meaningful commitment in a market where several competitors have exited or deprioritized on-premises development.
Why businesses choose Sangoma over 3CX
The decision usually comes down to a few operational outcomes that buyers consistently return to:
- Predictable costs from day one. Per-seat pricing, no hidden hosting, SSL certificate or support fees. The figure on the quote matches the figure on the invoice.
- Communications that stay active when the internet goes down. Local survivability, 4G failover and POTS backup mean a connectivity interruption does not become a communications outage.
- Full features without tier escalations. Voice, video, messaging, collaboration and contact center included with every seat; Switchvox Cloud adds an integrated contact center. No Enterprise plan required to unlock the features a team actually needs.
- A platform that manages itself. Updates, scalability, call routing and security managed by Sangoma on its private network. No SIP trunk management, patch schedule or SBC configuration.
- One provider, one support contact. Phones, SBCs, gateways, software and 24/7 support come from Sangoma. No multi-vendor troubleshooting.
- A proven track record. More than 10 consecutive years in the Gartner Magic Quadrant for unified communications, more than 40 years of industry experience and CSAT scores above 90 %.
- Compliance built in, not added on. PCI-certified, HIPAA-compliant private network for industries where data security is a regulatory requirement.
Switching to Sangoma is simple with minimal disruption
Sangoma manages migrations from 3CX and other PBX systems. Because the same software runs on-premises, virtual machines, cloud, and hybrid configurations, customers can change their deployment model later without relearning the platform. Multi-site businesses can add new sites quickly through the online partner portal. For teams still using older analog hardware, ATA compatibility and legacy device support means existing hardware does not necessarily need to be replaced on day one.
The best alternative to 3CX
For teams seeking enterprise-grade communications without the IT overhead of running a software PBX, Sangoma is the most direct alternative to 3CX. Per-seat pricing, fully managed infrastructure, an in-house hardware ecosystem, and included 24/7 support address the specific shortcomings that most often come up in 3CX purchasing discussions.
The best way to see how the numbers work for a specific organization is to speak directly with the Sangoma team. Book a call to get a quote or discuss migration options.

Sangoma vs 3CX: FAQ
Can Sangoma handle multi-site businesses without requiring an on-site IT resource at every branch?
Yes. Sangoma’s cloud platform is fully managed and monitored 24/7, with no on-site hardware requirements. New sites can be brought online quickly through the online partner portal. Local survivability options, including 4G failover and POTS backup, keep voice service running at each branch even if the internet connection goes down, without requiring an on-site technician.
Is 3CX’s simultaneous-call model ever cheaper than per-seat pricing?
It can be, in very specific scenarios: a small business with low, predictable call volume and in-house IT capacity to manage deployment. As call volumes grow, teams add sites, or competition becomes harder to predict, the simultaneous-call model tends to generate unexpected upgrade costs. Add hosting, SSL, and per-ticket support fees, and the total cost of ownership often exceeds what the license price suggests.
What happens to phone calls if the internet goes down at a branch office?
Sangoma supports local survivability through POTS backup and 4G failover, so a connectivity outage at a branch does not interrupt voice service. The platform also offers a 99.999% uptime guarantee on its own cloud, separate from connectivity at the branch level.
How difficult is it to move from 3CX to Sangoma?
Sangoma manages the migration process and includes high-quality onboarding in its standard support. Because the same Sangoma software runs on-premises, on VMs, and in the cloud, customers who later want to change their deployment model do not have to relearn the platform. ATA compatibility means some existing phone hardware can be transferred instead of being replaced immediately.
Is 3CX support included or does it cost extra?
3CX charges $75 per support ticket. Support is not included in the license. Sangoma includes 24/7 support with every seat at no additional cost.
Which platform scales more easily as the business grows?
Sangoma scales by seat. Adding a user means paying for an additional seat, and the platform handles the underlying capacity adjustment. 3CX requires recalculating the license based on simultaneous calls as staff and call volumes grow, and multi-site deployments require separate configuration for each site. For businesses planning to grow or add sites, Sangoma’s model is simpler to manage.
How do the two platforms compare in terms of uptime and reliability?
Sangoma’s cloud infrastructure offers a 99,999 % availability SLA with built-in redundancy and automatic failover. 3CX does not publish a comparable availability commitment; reliability depends on the hosting environment chosen by the customer and its configuration. 3CX users have reported unexpected feature deactivations during platform updates, adding operational risk for businesses that depend on specific features.
Can we keep our existing desk phones if we switch to Sangoma?
In many cases, yes. Sangoma supports ATA compatibility and flexible integration of third-party phones, which means some existing hardware can be connected rather than replaced immediately. Sangoma can advise on compatibility during the migration consultation. Customers who want to standardize on Sangoma’s own P‑Series phones receive a P325 with each Switchvox Cloud seat.
