The global PBX/IP PBX market continued to fall in Q2 2013, recording a decline of 4% year-on-year (period April to June 2013 inclusive) and a 1% decline sequentially.
The total market volume in Q2 2013 was the lowest witnessed in three years, according to MZA's latest report.
The largest declines were seen in the enterprise (solutions with more than 100 licenses) market, down 6% year-on-year, with a more moderate decline noted in the SME market (solutions with under 100 licenses).
According to MZA the greatest impact on the global PBX market came from the largest regional market Asia Pacific which suffered an 8% year-on-year decline in Q2 2013, influenced notably by a strong 15% decline in the 100-plus segment.
The markets in western Europe and Middle East and Africa fell relatively moderately, while the markets of Latin America and Eastern Europe suffered double digit declines year-on-year.
The north American market once again bucked the trend and grew by 7% year-on-year. The region also experienced a second successive period of sequential quarterly growth.
A strong performance in western Europe and north America has taken Avaya to number one position in the global PBX/IP PBX market, achieving a 13% volume share in Q2 2013.
Cisco, following several strong quarters, had a more challenging Q2 2013 and took the number two position with a 12% volume share.
"Avaya has a strong presence in both the SME and enterprise space, whereas Cisco's position is mainly attributed to its enterprise presence," stated Stephanie Watson, General Manager, MZA.
Meanwhile, Panasonic's performance, driven by its strong SME and Asia Pacific business, rebounded after a disappointing Q1 2013 taking the vendor to third position globally with 11% volume share.
NEC, with a good presence in both SME and enterprise segments, ranks fourth in the period with a 9% volume share. NEC's shipments fell back (most notably in its home Asia Pacific region) following a record Q1 2013.
Also in the running are Siemens, Alcatel-Lucent, Mitel, Aastra, Samsung and Microsoft. Siemens, Alcatel-Lucent and Aastra share a strong top four position in the European market but are placed lower in other global regions.
Mitel strengthened its north American position in Q2 2013, contributing to its market share growth.
Samsung's strong performance in Asia Pacific similarly contributed to overall market share growth for the Korean vendor.
Microsoft continues to make strong inroads into the enterprise market with a top six position in this segment already. But lesser presence currently in the SME space means its overall market share is lower.
Watson added: "The remainder of the market is fragmented and includes vendors Huawei, which has a strong position in both Asia Pacific and Middle East and Africa; and Ericsson-LG whose business is currently weighted towards their home Asia Pacific region.
"Similarly, Shoretel occupies a strong US position however its share at a global level is smaller resulting from its lower position in other global regions."
