In their own words
NTT Cloud Fax
NTT Cloud Fax is a paid web service that gives organizations a virtual fax number and handles inbound and outbound faxes through email. Users can send documents as email attachments, in the message body, or both, and receive incoming faxes as PDF attachments. Supported outgoing files include DOC, PDF, XLS, PPT, and TXT, with notices for successful or failed delivery. The service works with Microsoft Exchange or Gmail through an SMTP connector and does not support analogue fax devices. Incoming handling detects T.38 and T.30 protocols. Each line includes five outgoing fax email addresses by default; fax blasting, junk faxing, spam, broadcast fax, and other high-volume sending are prohibited. Listed destinations include the United States, United Kingdom, Australia, Canada, and Japan, while other destinations are charged per minute. NTT describes AES-256 encryption for personal data stored at rest longer than one hour and redundant high-availability clusters with stateful failover. Support is available in English 24/7 for elements under NTT control. Pricing is on request, with monthly line charges and per-minute overage billing.
