New research from telecom consultancy Software Advice states "the need to incorporate mobile devices into business communications infrastructures has spurred much of the recent evolution in PBX and unified communications systems". This allows company's to run without employee's tied to their desk because they now have the ability to get voice mail to e-mail, call from a mobile device using their desks extension, and other features that provide a consistent unified user-interface and user-experience across multiple devices and media types.
The graph below represents the comparison of the trends in different Unified Communications features. While the most popular terms are on a slow but steady decrease, terms like "mobility client" and "presence information" are increasing in popularity. These are both features that are gaining popularity with the increased knowledge of both SIP Trunking and VoIP systems.
Growth of SIP Trunking
Daniel Harris, VoIP and telecom researcher at Software Advice has spoken on the growth of SIP Trunking. "Industry experts confirmed that SIP would continue to be the basis for telephony solutions for the foreseeable future, and also predict that the evolution of Unified Communications will create a greater demand for SIP trunks. While the market has seen incredible growth over the past few years, our sources explained that SIP trunking is still years out from peak monetization."
The percentage of companies using SUP trunking will grow from 38% to 58% in 2015, according to a survey from Infonetics. Part of the push toward SIP Trunks is due to their "increased savings and scalability, when compared to traditional PSTN trunk lines: Businesses simply purchase additional bandwidth rather than additional trunk lines in order to add new employees to the phone system. This is one reason the market for SIP trunking has been growing by 50 percent annually." With this increase, we will see organizations getting smarter with their communications, integrating their business phone systems with software and mobile devices to increase their flexibility as a whole.
Growth of Cloud Based VoIP Systems
Jeff Valentine, CMO of Fonality, has been tracking the shift to Hosted PBX solutions. He estimates that "around one-fifth of the market today is willing to buy a hosted, cloud-based phone system, and the total share of the market that has bought is much smaller,” he explains. “I expect that within the next 10 years, however, this ratio will flip, and only one-tenth of potential buyers will be willing to consider an on-premise system."
Sofware Advice has done studies on Google Trends to back up Valentines predictions:
"Currently, only a tiny fraction of the voice traffic flowing over the public Internet is encrypted and even this traffic is often subject to interception. Thus, the industry experts [that were] interviewed predicted that securing VoIP will be one of the major technological initiatives in the industry over the next decade."
