Online Fax for VoIP Providers & UCaaS Companies
VoIP and unified communications providers manage number porting authorization forms, E911 registration requirements, interconnection agreements, and service level documents that still route through fax for carrier-to-carrier exchange. Number porting involves frequent LOA (Letter of Authorization) faxes between winning and losing carriers that require precise delivery documentation.
Common Documents
Compliance
VoIP providers must comply with FCC E911 obligations, number porting rules under LNPA, and CALEA wiretap requirements. Number porting LOAs must comply with FCC porting timeline requirements. E911 registration must be maintained for all served numbers. Send FAX Mail's documented transmission records support porting compliance documentation and E911 registration confirmation for regulatory examination.

VoIP & Unified Communications Fax — FAQ
Send FAX Mail handles large outbound fax volumes with flat-rate pricing. The Business plan covers 5,000 pages for $79.99/month, and the Enterprise plan covers up to 8,000 pages for VoIP carriers with very high porting activity.
Yes. Send FAX Mail provides dedicated inbound fax numbers with 24/7 receipt and immediate email notification. Porting team members receive notification of every incoming LOA as it arrives, eliminating paper queue delays.
The Enterprise plan at $169.99/month covers up to 8,000 pages/month — significantly less than dedicated fax server infrastructure and enterprise fax service contracts that high-volume carriers typically maintain.
