The most recent market numbers (2Q10) from the UK analyst firm MZA, as reporting on this UK website, find Avaya holding a small but noteworthy edge over Cisco in the global PBX market (thanks Sheila!) MZA shows Avaya at 15% share worldwide with its acquisition of Nortel Enterprise, compared with Cisco's 12%.
However, Cisco handily outpaces Avaya in the global market for IP extensions, winning 33% of the market, compared with 21% for Avaya.
According to this website's report, MZA paints a bleak picture of the market in Western Europe, and yet also shows encouraging signs, reporting a 16% Y/Y growth in the quarter ending with June.
The global market was coming off a very difficult 2009, as described by Melanie Turek on this recent No Jitter blog summarizing Frost & Sullivan findings.
MZA's global market share figures are close to the picture painted by Allan Sulkin in this No Jitter post. Allan's 1Q figures likewise show Avaya with a narrow lead in the global market.
