We retired 38 analog fax machines across our network and moved every clinic to Abbax Cloud Fax in six weeks. Inbound referrals now attach to the right Epic chart automatically — our intake team cut document handling from 14 hours a week to under 2. The BAA was signed on day one.

A few things you might want to know about Cloud Fax.

Can't find an answer? Talk to our team → or check our Help Center →

What is cloud fax and why is it essential for healthcare organizations?
Cloud fax replaces analog fax machines and dedicated phone lines with a secure, internet-based service. For healthcare organizations, it's essential because fax remains the dominant method for transmitting referrals, lab orders, and consent forms between providers — but legacy fax is slow, expensive, and not encrypted in transit. Cloud fax keeps the universal protocol every clinic understands while adding HIPAA-grade encryption, audit trails, and automation.
Is Abbax's cloud fax solution HIPAA compliant?
Yes. Abbax Cloud Fax is HIPAA-compliant by design. A signed Business Associate Agreement (BAA) is included on every plan — not just enterprise. We're SOC 2 Type II audited annually, use FIPS 140-2 validated encryption modules, and maintain immutable audit logs of every transmission for 7 years.
How does Abbax protect patient health information (PHI)?
PHI is encrypted at rest with AES-256 and in transit with TLS 1.3. Access is gated by role-based permissions and SSO. Every read, send, and download is logged. We offer US-only data residency on request, automatic PHI redaction for non-clinical downstream workflows, and the ability to enforce zero-retention policies on transmitted documents.
Can cloud fax replace traditional fax machines?
For most workflows, yes. Browser, desktop, email, and print-to-fax surfaces cover every way a staff member sends a document today. For sites that prefer to keep an existing machine, our Fax Machine Connector bridges any T.38 device to the cloud — so you can decommission your analog phone line without retraining staff.
Why do healthcare organizations still rely on fax instead of email?
Fax has universal acceptance among healthcare providers, a built-in delivery confirmation, and well-understood compliance precedent. Email between providers requires direct messaging protocols (Direct Trust) that have lower adoption. Fax also produces a clear legal record of transmission — which is why CMS, state regulators, and most payers continue to require it.
Can cloud fax integrate with EHR and EMR systems?
Yes. We ship native integrations for Epic, Cerner, Athenahealth, eClinicalWorks, NextGen, and Allscripts. Inbound faxes attach to the correct patient chart automatically using OCR-extracted identifiers. Outbound faxes can be triggered from within the EHR via context menu or REST API. For custom EHRs, our HL7 and FHIR endpoints handle the rest.
How does cloud fax improve healthcare efficiency?
Three ways: (1) Automation — covers, documents, and signatures assemble themselves, so staff don't manually print, sort, and stamp. (2) Routing — inbound documents land in the right chart or queue without a human triaging them. (3) Visibility — every fax has live status, retries automatically, and never sits unsent on a desk overnight.
Is cloud fax reliable at healthcare scale?
Yes. We process over 5 million pages per month across multi-site hospital networks and national specialty practices. Our infrastructure has a 99.99% uptime SLA on Enterprise, geographic redundancy across three US regions, and automatic carrier failover so a single carrier outage doesn't interrupt your transmissions.
Does cloud fax support auditing and compliance reporting?
Yes. Every fax — inbound, outbound, attempted, retried — generates an immutable audit record retained for 7 years. Reports can be exported by date range, user, patient identifier, or document type, and we provide pre-built compliance reports for HIPAA Security Rule, SOC 2, and internal audit committees.
How quickly can healthcare organizations adopt cloud fax?
Single-site clinics are usually fully migrated in under a week — including porting your existing fax number. Multi-site hospital networks typically complete a 25–50 site rollout in 4–8 weeks, with our healthcare implementation team handling EHR integration, staff training, and number porting in parallel.
