OTG Networks vFax

OTG Networks vFax is a cloud fax service for sending and receiving faxes through email or a browser. It is best suited to organizations already on GoOTG that need managed fax numbers and HIPAA-oriented controls. Its clearest advantage is that GoOTG includes it at no extra charge; as a standalone purchase, the pricing picture is less compelling.

Overview

vFax removes the need for fax hardware while keeping familiar email and browser workflows. Users can send and receive faxes, obtain a local or toll-free number, or port an existing number. This is a practical fit for teams that still exchange faxes but do not want a physical machine; those seeking a clearly priced, standalone fax subscription may prefer a service with more transparent fax-specific plan terms.

Key features

Email sending is straightforward: attach a PDF and enter the fax number in the recipient field. Incoming faxes arrive as PDF attachments, which should suit teams that already route work through email, though the described workflow is centered on PDFs.

The browser portal supports drag-and-drop document sending, fax history, and management of multiple numbers. A dedicated local or toll-free number, or the option to port an existing number, helps businesses retain a familiar fax identity. Delivery receipts record the timestamp, pages delivered, and recipient confirmation, giving teams a useful transmission record.

OTG says faxes are encrypted in transit and at rest, with role-based access controls and audit logs. It describes vFax as HIPAA compliant and cites 256-bit encryption, full audit logs, and SOC 2 readiness. Those measures make it relevant to regulated work, but they do not alone ensure that an organization's practices meet its compliance obligations. Unlimited cloud storage removes a stated storage ceiling.

OTG's ecosystem includes Salesforce, HubSpot, Microsoft Teams, Zoho CRM, Slack, WhatsApp API, Google Workspace, and Active Directory. Support hours are Monday through Friday, 8 AM–8 PM EST, and Saturday, 10 AM–4 PM EST.

Pricing

The vFax plan is free and includes a dedicated local or toll-free fax number plus sending and receiving. More importantly for buyers already considering OTG's phone service, vFax is included free on every GoOTG plan with no extra fees stated on its page.

GoOTG Starter costs $15 a month, billed month-to-month. It includes unlimited calling, voicemail transcription, mobile and desktop apps, basic analytics, and email support. It is the lower-cost entry point, but its stated support is email rather than priority support, and its analytics are basic.

GoOTG Business costs $29 a month, billed month-to-month. It adds AI-powered call routing, advanced analytics, CRM integrations, call recording, and priority support, making it the better fit for organizations that need those calling and support features. Enterprise has custom pricing and includes a dedicated account manager, custom integrations, SLA guarantees, advanced security, and vFax. The GoOTG plans are broader phone-service bundles, so readers comparing fax services should weigh their need for the wider bundle rather than treating them as fax-only tiers.

Platforms

vFax supports Android, iOS, macOS, web, and Windows. Mobile apps extend access beyond the browser and email workflows, while the broad desktop and web coverage suits teams using different devices.

Who it's for

Healthcare, legal, finance and banking, and real estate are the industries OTG identifies as relying on vFax. It is most persuasive for organizations in those sectors that need faxing alongside GoOTG, especially where number management, delivery records, and HIPAA-oriented controls matter. A small team seeking only occasional outbound faxing may find a free, page-limited service a better match.

Pros and cons

• Pro: vFax is included free on every GoOTG plan, so existing GoOTG customers can add faxing without an extra stated fee.
• Pro: Email and browser sending, inbound PDF delivery, and number porting cover common business fax workflows without hardware.
• Pro: Delivery receipts and audit logs provide records that matter when teams need to track transmissions.
• Con: The paid GoOTG tiers bundle calling and other features, which may be unnecessary overhead for buyers who only want faxing.
• Con: Enterprise uses custom pricing, and the provided plan terms do not give fax-specific page quotas or seat counts for the paid tiers.

Verdict

Choose vFax if your organization already uses GoOTG and needs business faxing with managed numbers, delivery records, and HIPAA-oriented controls: inclusion at no extra stated fee is its strongest reason to choose it. Look elsewhere if you want fax service alone with clearly defined page quotas and standalone pricing.
