When a business starts shopping for a phone system replacement, Sangoma and 3CX tend to land on the same shortlist. Both serve businesses replacing aging phone systems. Both handle voice, video, and messaging. Both show up in the same search results. On a feature checklist, they look like close competitors.
They aren’t. The two platforms ask fundamentally different things of the buyer, and that difference determines which one fits.
3CX is a software-based IP PBX. The customer or a channel partner hosts it, configures it, scales it, and keeps it running. Sangoma is a fully managed business communications platform with cloud, hybrid, or on-premises deployment options, built and operated on its own infrastructure.
One company hands the buyer a toolkit. The other hands them a working phone system.
Buying conversations between the two phone system providers come down to three specifics: 3CX’s simultaneous-call billing model (concurrent calls, not seats), the customer-managed responsibilities across all 3CX deployment types, and a cost stack — hosting fees, SSL certificates, $75 support tickets — that isn’t obvious from the license price. The sections below work through each one.
Sangoma vs 3CX: Key Differences at a Glance
The table below covers the core decision factors. Each row is a short, factual statement. 3CX has genuine strengths worth acknowledging: deployment flexibility across self-hosted, partner-hosted, and cloud-hosted configurations; web conferencing support for up to 300 participants; and an advanced PBX feature set suited to SMBs that want fine-grained call control. The fuller picture follows in each section below.
| Factor | Sangoma | 3CX |
|---|---|---|
| Pricing model | Per seat, all-inclusive | Per simultaneous call (SC) |
| Cost predictability | Fixed monthly per user | Variable; depends on concurrency |
| Support cost | 24/7 included at no extra charge | $75 per support ticket |
| SIP trunking | Built-in (SIPStation) or fully managed | Customer-sourced separately |
| Hosting cost | Included in cloud plans | $250–$2,000 annually |
| Deployment management | Fully managed by Sangoma | Customer or partner-managed |

| Contact center | Built-in with Switchvox Cloud; no extra license. | Add-on |
| Gartner recognition | 10+ consecutive years in Magic Quadrant for UC | Not cited |
Pricing Models That Don’t Compare Apples to Apples
The two business communications platforms use fundamentally different billing structures, and the difference matters most when a business starts growing or running higher call volumes.
How 3CX Pricing Works
3CX licenses by simultaneous calls (SC), the number of calls active at any one moment, rather than by user. In partner-led sales this model is flexible: a partner buys SC capacity in volume and repackages it into per-seat pricing for the end customer, so the business buying the system often sees a familiar per-user rate regardless of the underlying SC licensing. How it nets out depends on how the partner structures the deal.
The cost picture diverges from a fully managed platform in the stack around the license, not the license model itself. SIP trunking is sourced and managed separately. Hosting runs roughly $250 to $2,000 a year depending on configuration. SSL certificates are a separate line item. Support is billed per ticket, with $75 per case cited in partner materials, so troubleshooting cost rises with the number of issues opened. None of these show up in the headline license price, which is what makes a like-for-like comparison against an all-inclusive per-seat plan hard to do from the quote alone.
How Sangoma Pricing Works
Sangoma bills per seat. Every user pays the same 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 hosting add-on, no SSL fees, no per-ticket support charges.
One point buyers often miss: even the 3CX-hosted option still requires customers to source, set up, and manage their own SIP trunks. “Hosted” in 3CX’s model does not mean fully managed.
| Cost Factor | Sangoma | 3CX |
|---|---|---|
| Pricing model | Per seat | Per simultaneous call |
| Per-user cost predictability | Fixed; same price regardless of volume | Variable; tied to peak concurrency |
| Support cost | Included 24/7 | $75 per ticket |
| SIP trunk cost | Not needed with cloud; on-prem Switchvox requires a separate SIP trunk, available via SIPStation | Customer-sourced, additional cost |
| Hosting cost | Included in cloud plans | $250–$2,000 annually |
| SSL / security cost | Included | Additional charge |
| Hardware / setup cost | P325 included with Switchvox Cloud seats | On-site technician truck roll; labor often exceeds $500 per phone |
Deployment Flexibility for Different Operational Needs
Both communications platform vendors offer multiple deployment paths. The difference is in how much of the work lands on the customer.
3CX’s three options (3CX-hosted, self-hosted on AWS or Azure, and partner-hosted) each 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-location rollouts require license recalculation and reconfiguration for each site.
Sangoma’s cloud and hybrid deployments are managed end-to-end, including updates, scaling, and call routing. Switchvox Cloud runs on Sangoma’s own infrastructure with no on-site hardware requirements. The same software (Switchvox) runs across on-premises and virtual machine, which means moving between deployment models does not require relearning the platform.
3CX suits teams with strong in-house IT capability or a trusted reseller relationship willing to own the configuration work. Sangoma suits operations teams that want communications running without a dedicated PBX administrator.
| Deployment Option | Sangoma | 3CX |
|---|---|---|
| Cloud-hosted | Fully managed by Sangoma 24/7 | Customer manages SIP trunks and configuration |
| Self-hosted (AWS, Azure) | Supported | Requires significant in-house IT expertise |
| On-premises | Supported | Customer-managed end-to-end |
| Hybrid (cloud + on-prem) | Yes, with local survivability options | Not a native option |
| Multi-location rollout | Quick site turn-ups via online partner portal | Requires license recalculation per location |
| Migration between deployment types | Same software across on-prem, VM, and cloud with minimal learning curve | Different configurations per deployment type |
What It Takes to Keep Each Platform Running
Once a phone system is live, the ongoing maintenance burden is often where the real cost of ownership shows up.
3CX customers manage system updates, scaling, and certain maintenance tasks themselves unless a partner has taken that work on. SIP trunk management falls to the customer in all deployment configurations. 3CX users have reported unexpected feature disabling in new platform versions, including smartphone push notifications and sudden reductions in free license channels. For businesses that rely on specific functionality day to day, that kind of unpredictability creates real operational risk.
Sangoma handles all of that on the customer’s behalf: updates, scaling, call routing, and security patching, all on its own private network. The operational model is designed for teams without a dedicated PBX admin.
| Responsibility | Sangoma | 3CX |
|---|---|---|
| System updates | Managed by Sangoma | Customer or partner-managed |
| Scaling and capacity | Managed by Sangoma | Requires license recalculation |
| SIP trunk setup and management | Included (SIPStation) or managed | Customer-sourced and managed |
| Call routing and configuration | Managed by Sangoma | Customer or partner-managed |
| Security patching | Managed by Sangoma | Customer-managed |
Hardware Ecosystem: Single Vendor vs. Multi-Vendor
3CX deployments typically require third-party hardware at several points: Session Border Controllers 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 route through a single vendor. IT teams manage fewer procurement decisions, fewer compatibility issues, and one support contact instead of several.
| Hardware Element | 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 trunking | Built-in SIPStation (auto-configured for on-prem) | Customer-sourced separately |
| Legacy device support | ATA compatibility, third-party phone integration | Limited |
| Phone branding | Configurable with company logo | Not available |
| Vendor relationships to manage | One | Multiple |
Compliance and Network 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, get that compliance posture built into the platform rather than something they have to configure and maintain separately.
3CX customers who self-host on AWS, Azure, or on-premises are responsible for their own security stack, patching cadence, and compliance configuration. The platform does not provide a compliant-by-default infrastructure; that work falls to the customer or their partner.
Feature Sets and User Experience
Sangoma ships a full communications suite — voice, video, messaging, and collaboration — with every seat at no extra license cost. Switchvox Cloud goes further, with a departmental contact center built in. Users get the tools they need from day one without tier-gating.
3CX’s standard plan is feature-limited. Most useful capabilities require upgrading to Pro or Enterprise tiers, which adds cost and complexity to an already layered pricing structure.
On user experience, 3CX’s admin interface reflects its origins as a traditional PBX and is less intuitive compared to modern UCaaS platforms. Sangoma is designed for non-experts to deploy and configure without dedicated IT resources.
Quality of Support
3CX’s support packages are sold separately and priced per ticket at $75 per case. Sangoma includes 24/7 support with every seat at no extra charge, backed by dedicated platform engineers and white-glove installation.
The results show up in the numbers. Over one measurement period, Sangoma’s support team lifted CSAT from 73.8% to 94.6%+ and added nearly 29 points to NPS, improvements attributed to a company-wide “One Sangoma” customer experience initiative. Partners and customers describe the team as a “safe pair of hands” when reliability matters most. 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-prem development.
Why Businesses Pick Sangoma Over 3CX
The decision usually comes down to a few operational outcomes buyers keep coming back to:
- Predictable costs from day one. Per-seat pricing, no hidden hosting, SSL, or support fees. The number on the quote matches the number on the invoice.
- Communications that stay up when the internet goes down. Local survivability, 4G failover, and POTS fallback mean a connectivity disruption does not become a communications outage.
- Full features without tier-gating. Voice, video, messaging, collaboration, and contact center ship with every seat; Switchvox Cloud adds a built-in contact center. No Enterprise plan required to unlock the features a team actually needs.
- A platform that manages itself. Updates, scaling, call routing, and security are handled by Sangoma on its private network. No SIP trunk management, no patching schedules, no SBC configuration.
- One vendor, one support contact. Phones, SBCs, gateways, software, and 24/7 support all come from Sangoma. No multi-vendor troubleshooting.
- Proven track record. Over 10 consecutive years in the Gartner Magic Quadrant for Unified Communications, 40+ years of industry experience, and CSAT scores above 90%.
- Compliance built in, not bolted on. PCI-certified, HIPAA-compliant private network for industries where data security is a regulatory requirement.
Switching to Sangoma Is Straightforward With Minimal Downtime
Sangoma handles migrations from 3CX and other PBX systems. Because the same software runs across on-premises, virtual machine, cloud, and hybrid configurations, customers can change deployment models later without relearning the platform. Multi-location businesses can add new sites quickly through Sangoma’s online partner portal. For teams currently running older analog equipment, ATA compatibility and legacy device support mean existing hardware does not necessarily need to be replaced on day one.
The Best 3CX Alternative
For teams that want enterprise-grade communications without the IT overhead of running a software PBX, Sangoma is the most direct alternative to 3CX. The per-seat pricing, fully managed infrastructure, in-house hardware ecosystem, and included 24/7 support address the specific gaps that come up most often in 3CX buying conversations.
The best way to see how the numbers work for a specific organization is a direct conversation with the Sangoma team. Book a call to get a quote or discuss migration options.
Sangoma vs 3CX: FAQs
Can Sangoma handle multi-location businesses without needing an on-site IT resource at each branch?
Yes. Sangoma’s cloud platform is fully managed and monitored by Sangoma around the clock, with no on-site hardware requirements. New sites can be turned up quickly through the online partner portal. Local survivability options, including 4G failover and POTS fallback, keep voice service running at each branch even if the internet connection goes down, without requiring a technician on the ground.
Is 3CX’s simultaneous call model ever cheaper than per-seat pricing?
It can be, in very specific scenarios: a small business with a low, highly predictable call volume and in-house IT capacity to manage the deployment. As call volumes grow, as teams add locations, or as concurrency becomes harder to forecast, the simultaneous-call model tends to generate unexpected upgrade costs. Add the hosting, SSL, and per-ticket support fees, and the total cost of ownership frequently exceeds what the headline license price suggests.
What happens to phone calls if the internet goes down at a branch office?
Sangoma supports local site survivability through POTS fallback and 4G failover, so a connectivity disruption at a branch does not take voice service down. The platform also carries a 99.999% uptime guarantee on its own cloud infrastructure, which is separate from branch-level connectivity.
How difficult is it to switch from 3CX to Sangoma?
Sangoma handles the migration process and includes white-glove installation as part of its standard support. Because the same Sangoma software runs across on-premises, virtual, and cloud configurations, customers who later want to change deployment models do not have to relearn the platform. ATA compatibility means some existing phone hardware can be carried over rather than replaced immediately.
Is 3CX support included or does it cost extra?
3CX charges $75 per support ticket. Support is not bundled with the license. Sangoma includes 24/7 support with every seat at no additional charge.
Which platform scales more easily as the business grows?
Sangoma scales on a per-seat basis. Adding a user means paying for one more seat, and the platform handles the underlying capacity adjustment. 3CX requires license recalculation based on simultaneous calls as headcount and call volume grow, and multi-location rollouts need separate configuration per site. For businesses that expect to grow or add locations, Sangoma’s model is more straightforward to manage.
How do the two platforms compare on uptime and reliability?
Sangoma’s cloud infrastructure carries a 99.999% uptime SLA with built-in redundancy and automatic failover. 3CX does not publish a comparable uptime commitment; reliability depends on the customer’s chosen hosting environment and configuration. Users of 3CX have reported unexpected feature disabling in platform updates, which adds a layer of operational risk for businesses relying on specific capabilities.
Can we keep our existing desk phones if we switch to Sangoma?
In many cases, yes. Sangoma supports ATA compatibility and flexible third-party phone integration, which means some existing hardware can be connected rather than replaced outright. 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.
