Frequently Asked Questions
Fax over IP (FoIP) is a telecommunications technology that helps you send and receive fax transmissions over IP networks (such as the internet or local intranets) rather than traditional PSTN (Public Switched Telephone Network) copper lines, drastically reducing hardware dependency.
The T.38 protocol is specifically engineered to protect fax data transmissions across packet-switched IP networks. It mitigates common VoIP issues like packet loss, network jitter, and latency, ensuring that heavy fax documents are delivered reliably without signal degradation.
A robust FoIP architecture consists of cloud-based fax servers, SIP proxy or SIP trunk providers for external routing, Media Gateways to bridge IP and analog signals, T.38 relay servers for packet protection, and Analog Terminal Adapters (ATAs) to connect legacy fax machines.
FoIP software integrates with enterprise CRM and Document Management Systems via open APIs. This allows users to trigger outbound faxes directly from customer records and automatically logs inbound faxes as digital files within the corresponding client account history.
Migrating to a Virtual Fax Server eliminates the need for dedicated PSTN lines and physical fax machine maintenance. It centralizes document management, reduces telecom overhead, enables remote faxing via email or mobile apps, and ensures secure, cloud-based disaster recovery for compliance.
