Fax server software, fax appliances, multi-functional devices and Internet fax services are transforming into Fax over IP servers and cloud faxing solutions.  These offerings are sometimes also coined IP Fax or VoIP Fax.  Globally, enterprise class organizations and carrier offerings are driving an improvement of the IP networks to increase overall reliability, bandwidth and relevance for the new and exciting technologies offered by SIP Trunking.  In the midst of these IP network improvements are SIP and SIP trunking discussions as a compliment to VoIP implementations, ultimately a migration strategy away from traditional PSTN (TDM networks). 

The SIP protocol is used to establish, initiate, modify and terminate communication sessions for voice, web conferencing, multimedia and more recently, fax communications.  SIP, which stands for “Session Initiation Protocol” is a simple text-based application layer protocol heavily influenced by SMTP and HTTP protocols. SIP thus is considered scalable, architecture friendly and reasonably easy to deploy. SIP is also an RFC standard RFC 3261 from the IETF.


The FoIP SIP Relationship
On the surface, FoIP enabled fax servers, fax service SaaS providers, media gateway devices and media traffic management vendors are encouraged by the SIP offering, but most are aware of challenges when it comes to T.38 or G.711 support for bi-directional fax communication and transmission across disparate carrier IP networks.  Challenges include interoperability, latency, jitter, packet loss, QOS and ECM support.
The good news for the spectrum of enterprise class organizations down to small business looking to deploy Fax over IP as part of a VoIP carrier offering is the maturing relationship between FoIP protocol requirements and SIP trunk vendors, largely in part due to efforts from a host of software vendors and hardware manufacturers including Commetrex, Cisco Systems, Dialogic (Brooktrout), Audio Codes, Sagemcom, Digium, Faxcore, Network Equipment Technologies, Acme Packet and more.  AllAboutFoIP.com should also acknowledge the efforts of the SIP Forum and its FoIP Task Group led by Marc Robbins.  The SIP Forum FoIP Task Group is working on a variety of issues including SIP, T.38 problem statements and T.38 amendment recommendations for the IETF.  Finally, it is important to note that the bar is raised by such SIP trunking carrier organizations as Global Crossing, babyTEL, Broadview, BroadVox and Node4, who lead the charge in certifying their VoIP network segments consider Fax over IP compliance.
