Why SignalWire?

Unified experiences across all channels.
No fax machine required.

Bring AI, voice, messaging, video, and fax together to create a programmable unified communications (PUC) experience for your users. Built by the world’s top telephony engineers - the creators of FreeSWITCH - our products are designed to work together seamlessly, so you can create innovative applications in infinite ways.

PUC is the future of telecom, representing a fusion of programmable interfaces and unified communication platforms. PUC platforms, like SignalWire's Call Fabric, offer customizable, easy to use, highly scalable solutions for both internal and external communications.

Status updates with real-time webhooks
Status updates with real-time webhooks

Use webhooks to notify applications of fax-related events (queued, sent, failed, received) in real-time. Get status updates when a fax is successfully delivered or fails, automatically trigger workflows when a fax is received, and track multi-page transmissions in real time.

Legacy telecom integration
Legacy telecom integration

SignalWire bridges modern programmable faxing with legacy telecom infrastructure, making it easy to integrate traditional PSTN-based faxing with cloud-based fax solutions. Migrate from on-premises fax servers, analog fax machines, or SIP-based fax systems.

Flexible numbering and BYOC
Flexible numbering and BYOC

Dedicated fax numbers are available, or you can port existing fax numbers to maintain continuity while upgrading to cloud faxing. SignalWire allows you to bring your own carrier (BYOC) to keep your carrier while using the Programmable Fax API and taking advantage of cloud-based storage.

Secure Transmission

Fax securely transmits documents using the telephone network and requires peer-to-peer direct connectivity prior to transmission of data, eliminating common attacks used with other transport mechanisms.

Financial Documents

Fax signatures are secure for the highly regulated world of financial institutions, particularly across geographies. Even without a fax machine, the Fax API allows for the processing of claim forms and loan applications.

Health Information

Because of incompatibilities across other electronic medical record systems, fax is commonly used for exchanging protected health information among physicians and for processing of claim forms.

Systems Integration

Integrate across horizontal applications, including ERP, CRM, and email systems to handle ad hoc document workflows even when customers, partners, and suppliers are not yet capable of richer document exchange.

Real Estate

Securely send and receive crucial documents like contracts, agreements, and property disclosures directly from computers, eliminating the need for physical fax machines and improving operational efficiency.

Ed Tech

Manage and transmit a wide array of documents, from student records to curriculum materials. With robust security measures, fax ensures the confidentiality and integrity of sensitive educational data, making it an ideal choice for modern educational settings.
