Dis-Unification and the tumble of SIP into legacy. How UComs never happened.
Dis-Unification and the tumble of SIP into legacy. How UComs never happened. by Martin Steinmann
The term "unified communications" emerged in the mid-1990s, when messaging and real-time communications began to combine. The vision of an all-integrated and unified communications system was appealing.
Today, 20 years later, we are looking at an industry in rapid fragmentation. SIP, the standard intended to unify it all is tumbling into legacy. PBXs are still PBXs and the evolution of these platforms to deliver a multitude of services has not happened, or at least customers have hesitated to buy all the different service add-ons the PBX vendors made available on their platforms.
A chasm has opened up between those still waiting for UC to take off, and those who have moved on convinced that communications has already turned into a feature of the Web.
Nobody denies that phones are still necessary and that there will be a long tail on the phone industry. But the numbers are clear: The PBX industry has been contracting for some time and in spite of considerable effort to remake, rebrand, and reposition, only few companies have turned the corner. The divide between telephony and data goes deep inside the channel and persists to this day.
UCaaS, or telephony from the cloud, is the new growth area. But looking at the Gartner Magic Quadrant report for UCaaS paints a different picture. While demand for UCaaS is picking up, overall adoption is way too low given that this offering has been around for about a decade. Penetration of UCaaS in the enterprise space remains low, while the opportunity to replace on-premises PBXs seems huge.
The reality is that there still is no good cloud-based replacement for an on-premises PBX, at least not for larger enterprise. Customers continue to sweat their assets, reluctant to invest, but forced to maintain their maintenance contracts. UCaaS will accelerate its growth, but it will remain significantly below its potential of taking over from the PBX era. Its overall addressable market is shrinking, which started to put a cap on demand.
At the same time users transition to other means of communication. Alternatives to desk phones are many. Users go mobile or use Skype or the many Skype look-alikes. Users also transition to more informal means of communication like chat and all forms of activity streams.
The Web is now the final frontier for dis-unification. It is the ultimate disaggregation of unified communications, creating a fragmented market where communications turns into a feature. No longer a stand-alone product, the ability to real-time communicate, whether with voice, video, screen sharing, chat, or otherwise, turns into a table-stakes feature for more and more Web applications. The arrival of WebRTC paved the way for the Web to take over. The SIP protocol, created at significant effort as a standard for all parties to interoperate in a unified communications world, is no longer necessary. Even the need for a standard has vanished. In fact, WebRTC explicitly does not standardize the signaling protocol used between end-points.
The browser in all its forms is the new universal client. With its ability to load the required software to communicate with a certain server or other party on demand, that software no longer has to follow a standard. Web developers use the path of least resistance to create the services users want at ever increasing speed, and they use technologies that make software development easy. Instead of complicated SIP interactions, these applications rely on JSON messages that can be as proprietary as they need to be. The user who wants to participate in a real-time interaction points the browser at a URL, loads the required software in the form of JavaScript, and establishes the connection. Done.
The PSTN and the PBX will stay where they always were. Dis-unification has obsoleted them as platforms for unified services. However, they will have a long life as gateways between the new and the old, providing universal reachability between the new fragmented world of Web-based communications and old telephony devices.
The bottom-line seems to be that users want to collaborate and not just communicate. Such collaboration happens using the applications and tools made for the specific type of work, and these tools are now expected to offer real-time communications as a feature. As simple as that.
