Chinese telecom network major Huawei is the leader in the global VoIP and IMS market with 28 percent share in 2015 against 20 percent share by Ericsson.
Alcatel-Lucent has 19 percent share. Genband has 6 percent and Nokia has 5 percent share of the worldwide VoIP and IMS market.
Telecom service provider voice over IP (VoIP) and IP multimedia subsystem (IMS) revenue rose 31 percent to $5.5 billion in 2015, according to IHS Inc.
The growth driver was investment in the voice over LTE (VoLTE) business. 48 telecom operators — 23 in Asia Pacific, 20 in EMEA (Europe, Middle East and Africa) and 5 in North America — have launched commercial VoLTE services as of January 2016.
“In 2015, the global carrier VoIP and IMS market posted its best result on record as VoLTE launches in EMEA and Asia Pacific drove activity,” said Diane Myers, senior research director for VoIP, UC and IMS at IHS.
In Asia Pacific, volumes were driven by Chinese telecom operators building up for VoLTE launches and providers in India getting ready for 2016, the results of the accumulation of activity we saw building throughout the year.
In the fourth quarter of 2015, the global telecom service provider VoIP and IMS market fell quarter on quarter to $1.4 billion.
Session border controllers (SBCs), voice application servers and IMS core elements posted solid year-over-year growth.
IMS equipment revenue (not including SBCs) accounted for 65 percent of VoIP and IMS revenue in Q4.
Ericsson, Alcatel-Lucent, Huawei, ZTE and BroadSoft achieved 35 percent year-over-year revenue growth in 2015.
