Worldwide UC&C Revenues Grew 6.9% in Q2 2023 While the CPaaS Market Grew 13.2%, According to the IDC Unified Communications and Collaboration Tracker

NEEDHAM, Mass.–(BUSINESS WIRE)–#CPaaS–Worldwide revenues in the Unified Communications & Collaboration (UC&C) market grew 6.9% year over year and 2.4% sequentially to $15.9 billion in the second quarter of 2023 (2Q23), according to the International Data Corporation (IDC) Worldwide Quarterly Unified Communications and Collaboration Tracker. For the full year 2023, worldwide UC&C revenue is forecast to grow 8.6% year over year to $64.7 billion. This represents an upward revision of roughly $500 million from the previous quarter’s forecast. In volume terms (units/lines/licenses/seats), the worldwide UC&C market grew 11.4% year over year and 2.9% sequentially in 2Q23 to 620.7 million. Compared to the previous quarter, the gap between value and volume growth rates expanded further, indicating continued downward pricing pressure per unit sale.

“Remote collaboration needs continue to grow and evolve with the changing dynamics led by the return to work, coupled with new innovation from vendors, especially on the AI front,” said Jitesh Gera, research manager, Unified Communications and Collaboration at IDC. “Moreover, public cloud Unified Communications as a Service (UCaaS) solutions integrated with telephony continue to be in strong demand as businesses increasingly look to unify their employee and customer communication channels with a strong foundation in voice. The hardware market is currently in flux, as vendors look to develop innovative meeting room equipment to offset the sharp declines in IP telephones and enterprise videoconferencing systems.”

Meanwhile, worldwide revenues in the Communications Platform as a Service (CPaaS) market grew 13.2% year over year and 4.6% sequentially to $3.8 billion in 2Q23, recovering from a sequential decline during the previous quarter. “This segment is evolving as buyers focus on tangible benefits as well as automation across a diverse range of channels,” said Courtney Munroe, research vice president, Worldwide Telecommunications Research at IDC. Although it is a challenging segment for CPaaS providers, Messaging continues to account for the bulk of the CPaaS market, sustaining its 67% share in 2Q23. For the full year 2023, CPaaS revenues are expected to grow 12.4% year over year to $15.6 billion a downward revision of $127 million from the 1Q23 forecast.
