Enterprise PBX revenue dipped 6 percent to $1.6 billion in the first quarter of 2015.
The drop in PBX — TDM, hybrid and pure IP — revenue was due to delay in new phone system purchases by enterprises, said the IHS Infonetics Enterprise Unified Communications and Voice Equipment report from IHS.
“The global enterprise PBX market remains challenging, with revenue down yet again in the first quarter of 2015. Pure IP PBX was the one segment to post year-over-year growth due to strength in Asia Pacific,” said Diane Myers, research director for VoIP, UC and IMS at IHS.
PBX line shipments rose 3 percent, while pure IP PBX line shipments grew 17 percent and hybrid IP PBXs accounted for around 60 percent of all lines shipped.
Sales of unified communications (UC) applications dropped 5 percent in Q1 2015 as enterprise spending remained conservative.
Top enterprise telephony vendors are Avaya and Cisco, while Microsoft dominates the UC market in Q1 2015.
