SIP adoption and implementation is rapidly increasing at all levels. The buzz around Internet Fax, Cloud Faxing and FoIP industries is SIP centered. Many consider the future of fax (not just fax over IP) revolves around SIP. The most common questions we are receiving at AllAboutFoIP.com are, "Who are the best SIP Trunk Providers for fax? Does SIP Peering matter with FoIP? Where do I turn if I have SIP interoperability issues? What are the best troubleshooting tools to use?"

The once uncharted waters of fax over IP in SIP Trunking environments are calming quickly. The best SIP Trunk providers for fax are those who have strategic partnerships or working relationships with fax server resellers, fax server software and hardware vendors, internet fax service providers and cloud faxing companies. Fax volume is increasing because it is still one of the most secure and reliable real-time methods of legal document exchange. There are more SIP Trunking providers “fax aware”, a wider variety of different fax over IP offerings and best practice recommendations. Organizations moving towards Unified Communications and SIP Trunking are intelligently asking the “What about fax?” question with higher degrees of technical detail as a part of their due diligence - instead of in hindsight.  Fax Server vendors that support fax over IP in SIP Trunking environments have better equipped their clients with webinars, white papers, internal technical teams and value added resellers that understand how to perform IP network analysis for fax and uncover interoperability issues between carriers that lack an agreed upon method of management or communications protocol standard for addressing jitter, latency and echo and cost accounting with SIP Peering.
