FAQ

Who develops and manages Fax Echo?

Fax Echo is developed and maintained by Tatsuya Moriguchi doing business as ModalFlo Mobile Solutions, focused on delivering secure, reliable, and mobile-first fax solutions. We aim to keep your fax workflow simple, private, and continuously improved based on user needs and feedback.

Who is Fax Echo for?

Fax Echo is designed for organizations that use eFax Corporate by Consensus Cloud Solutions (or an authorized reseller) and require secure mobile access to inbound fax communications.

To use Fax Echo, customers must:

• Maintain an active eFax Corporate account
• Configure users and permissions in the eFax Corporate Admin Portal
• Operate in environments where security, auditability, and controlled access are required

Fax Echo is not a standalone fax service and does not replace eFax Corporate. It functions as a secure mobile extension of an enterprise fax environment.

Organizations that need help with onboarding, configuration, or integration may engage ModalFlo Mobile Solutions to handle eFax Corporate setup and Fax Echo enablement as a paid outsourcing service.

Who Fax Echo may not be a good fit for:

• Solo practitioners or very small teams seeking a low-cost, all-in-one fax app
• Users without an existing or planned eFax Corporate deployment
• Organizations that do not require mobile approvals or compliance-oriented workflows

Can you customize Fax Echo to fit our workflow and operational needs?

Yes. Fax Echo can be customized to align with your organization’s specific workflows, field operations, compliance requirements, and staff processes. Rather than requiring a large upfront development fee, we offer customization and ongoing build management for a reasonable monthly engagement fee (starting at approximately $599/month, depending on scope and complexity).

What is eFax Corporate, and why do I need a separate account?

eFax Corporate is a secure, business-grade fax service that gives each user their own fax number and centralized management. Fax Echo is an iOS app that connects to your eFax Corporate account, making sending, receiving, and notifications faster and easier on your mobile device. Since Fax Echo doesn’t provide the fax SaaS service itself, you’ll need a separate eFax Corporate subscription and billing directly with Consensus Cloud Solutions or their authorized partner. This keeps your faxes secure and your account compliant.

Why is Fax Echo available on iOS only?

Fax Echo was initially developed for iOS to deliver a focused, high-quality mobile experience with strong platform-level security, reliability, and performance. iOS provides a mature ecosystem for secure app deployment, consistent device behavior, and long-term OS support, which made it an ideal starting point for Fax Echo.

This does not mean that Android or web applications are inherently insecure. Modern Android and web platforms can also be designed to meet high security and compliance standards when implemented correctly.

At this time, Fax Echo is offered as an iOS app to ensure a streamlined experience and maintain development focus. However, Android and web-based versions can be developed upon request for enterprise or partner customers, including tailored security, compliance, and deployment requirements. Please contact us to discuss platform availability and pricing.

Can we outsource eFax Corporate administration and support work?

Yes. ModalFlo provides comprehensive eFax Corporate administration and support, including account management, configuration updates, and troubleshooting.

Outsourcing your eFax administration frees your IT team to focus on core business operations, while ensuring your eFax environment is professionally maintained and compliant. Contact us to discuss a plan tailored to your organization’s needs and user base.

How does Fax Echo support HIPAA and other security requirements?

Fax Echo is designed with security and compliance in mind and follows a shared-responsibility model.

Fax Echo itself does not transmit or store fax documents independently. All fax transmission, storage, and core compliance controls are handled by the eFax Corporate platform, which is developed and operated by Consensus Cloud Solutions. eFax Corporate is certified and compliant with industry-recognized standards, including HITRUST and SOC 2 Type II, and aligns with requirements for HIPAA, GDPR, PCI DSS, and ISO 27001/27002.

Fax Echo provides a secure mobile interface to eFax Corporate using authorized APIs. The standard App Store version is designed to minimize local data retention and does not support document downloading or local storage. Organizations that require document downloads must use a separately developed, organization-specific version of Fax Echo, delivered outside the public App Store.

ModalFlo, the developer of Fax Echo, applies additional application-level security controls appropriate to its role, including secure authentication, access control, encrypted communications, and minimal data retention. When required, ModalFlo can enter into a Business Associate Agreement (BAA) for healthcare customers and a Data Processing Agreement (DPA) for organizations subject to GDPR.

In summary, Fax Echo leverages the certified and compliant infrastructure of eFax Corporate while adding its own security safeguards at the application level. This layered approach helps organizations meet their regulatory and security obligations without duplicating compliance efforts.

What do we need to do in our IT system in order to use Fax Echo?

In most cases, nothing at all.

Fax Echo is designed to work without requiring any changes to your existing IT systems, servers, or network infrastructure. There is no software to install on desktops, no VPN configuration, and no on-premises hardware to manage.

Fax Echo runs as a secure iOS mobile app and connects directly to eFax Corporate’s cloud service, allowing your users to send and receive faxes without involving your internal network.

How does this work from a network perspective?

• Fax Echo runs on iOS devices (iPhone or iPad)
• Mobile apps typically connect over cellular networks or standard internet connections
• Because of this, Fax Echo usually bypasses your corporate network entirely

Are there any exceptions?

The only situation where a small network change may be required is if:

• Your organization enforces strict Wi-Fi or mobile device network restrictions, and
• Outbound access is limited to an approved (allow-listed) set of URLs

In that case, your IT team may need to allow-list the eFax Corporate service URL so the app can communicate with eFax securely. No other firewall, proxy, or system changes are required.

Do we need to modify or integrate with any internal systems?

No. Fax Echo does not require:

• Changes to email systems
• Changes to fax servers or PBXs
• API integration with internal applications
• Changes to identity systems or databases

All fax processing is handled by eFax Corporate’s cloud platform, with Fax Echo acting as a secure mobile interface.

Why is this beneficial for IT teams?

• Zero infrastructure changes
• No disruption to existing workflows
• Fast deployment
• Minimal IT involvement
• Lower security and operational risk

This “no-touch IT” approach is one of the key reasons organizations adopt Fax Echo alongside eFax Corporate—users get mobile fax access immediately, while IT maintains full control without additional complexity.

What is not included in Fax Echo monthly subscription fee?

Professional services, administration support, and compliance agreements are offered outside the App Store and are not included in the Fax Echo app subscription.
