SOLUTION COMPARISON

InterFAX vs RingCentral

RingCentral’s RingEX and Upland InterFAX are both well-established communications providers with a global customer base. Where the two platforms diverge is in focus. RingCentral brings voice, video, messaging, SMS, and fax together in one application. InterFAX is built exclusively around cloud fax: compliance, HIPAA, AI-powered document processing, and enterprise integrations, all on a single platform designed specifically for fax as its primary use case.

For organizations in regulated industries where fax is a mission-critical function rather than a bundled feature among many, InterFAX’s distinction shows up in AI capabilities, pricing, broadcast scale, and document workflow depth. When comparing InterFAX vs RingCentral, InterFAX is the clear RingCentral alternative.

	Comparison Comparison
	HIPAA-Compliant Cloud Faxing HIPAA-Compliant Cloud Faxing Both InterFAX and RingEX support HIPAA-compliant faxing with BAA agreements available. If HIPAA compliance is the primary driver of your evaluation, both platforms meet that baseline; the differentiators lie elsewhere.
	AI Built for Fax Document Workflows AI Built for Fax Document Workflows InterFAX includes AI-powered data extraction, OCR/ICR, classification, summarization, translation, and intelligent routing as a native capability. It’s built specifically for the regulated document workflows that fax serves in healthcare, financial services, and insurance. RingCentral's AI Assistant is focused on administrative note taking, transcription, message translation, and meeting summaries. Their AI is built for communications productivity, not fax document processing.
	Pre-Paid Credit Packages with No Expiration Date Pre-Paid Credit Packages with No Expiration Date A pre-paid pricing model is available with InterFAX. Purchase credits at a volume rate and draw from that balance whenever you need them, with no clock running out. RingEX has no pre-paid option; fax is bundled into a per-user monthly seat, so your cost is fixed regardless of actual usage. For enterprise teams whose fax volume spikes around audits, open enrollment, or filing deadlines, InterFAX's pre-paid model aligns cost to activity rather than to a calendar.
	High-Volume Fax Broadcasting High-Volume Fax Broadcasting InterFAX supports broadcast faxing to up to 20,000 recipients with batch processing built in as a standard enterprise feature. RingEX mentions the ability to send multiple faxes at once but does not publish a high-volume broadcasting capability or recipient scale. For organizations that distribute faxes at scale, patient notifications, regulatory filings, insurance communications, the ability to confirm that capability before you commit is a reasonable expectation.
	Fax-Native Platform vs Fax as a Bundled Feature Fax-Native Platform vs Fax as a Bundled Feature InterFAX is built exclusively for cloud fax: every security control, compliance certification, integration path, and support model is designed around fax as the primary use case. RingEX is a unified communications suite where fax is one component alongside phone, video, SMS, and messaging. For regulated industries where fax carries legal, clinical, or financial weight, a platform where fax is the entire mission offers a depth of capability and accountability that a bundled communications suite is not designed to match.
	REST and SOAP APIs: Compatible with Every Infrastructure REST and SOAP APIs: Compatible with Every Infrastructure InterFAX supports both REST and SOAP APIs, making it compatible with modern cloud environments as well as legacy enterprise infrastructure alike. RingEX's fax API is REST only; organizations running SOAP-based systems, older ERP platforms, or applications built before REST became standard cannot integrate natively. Whether your infrastructure is fully modern or mid-transition, InterFAX connects without requiring your team to rebuild it first.

Questions to Ask

Fax is still a reliable and trusted tool in industries where privacy and compliance matter most—like healthcare, finance, and government. To protect sensitive information, it’s important to choose a solution like InterFAX, which meets strict global standards such as HIPAA and GDPR.

At InterFAX, data security is a top priority. Our platform offers inbound and outbound faxing with end-to-end encryption and customizable security settings to help your organization stay compliant: features you won’t find with providers like RingCentral.
Most cloud fax solutions just send documents, but InterFAX does much more. It turns faxes into usable data by automatically identifying, sorting, and delivering vital information like invoices, purchase orders, or patient records, without anyone needing to do it by hand. This leads to faster processing, fewer errors, and greater efficiency.

Unlike basic communication tools like RingCentral, InterFAX offers intelligent automation, real-time visibility, and smooth integration with your existing systems—helping your business work smarter, save time, and reduce costs.
Less manual work means better results. Really. With the right tools, digital workflows can speed things up, reduce errors, and keep processes moving smoothly. InterFAX does more than just send faxes: it automates the entire process. With InterFAX, faxed documents are automatically read, verified, and delivered to key systems like EHRs, ERPs, CRMs, or document management platforms.

Unlike RingCentral, which depends on extra automation tools, InterFAX offers an all-in-one, intelligent solution: making it a smarter, more efficient alternative to the competition.
If efficiency matters to you, the answer is YES. Integration is key to ensuring that faxed documents flow smoothly into your existing systems. Without it, teams are stuck manually downloading, sorting, and entering data: slowing things down and increasing the chance of mistakes.

InterFAX makes integration easy with a flexible Developer API, allowing your systems to automatically process, extract, and route faxed documents in real-time.

It integrates nicely with our CRM and works great. We had RingCentral in the past, but this is much better. Customer support was great with setting it up.
