The Linux-based Zultys IP-PBX systems value proposition was an integrated hardware-software system that removed the complexity associated with installing and managing disparate telephony components.

Looking back, Warhust said the demise of Zultys here came as such a shock to staff and resellers because "we were growing at a phenomenal rate and looking at a A$4 million (US$3 million) quarter last quarter".

At this point there is no Pivot office here but only resellers, to whom Warhust recommends "just hang in there and wait for Pivot but if you're unsure, contact me".

Warhust is now South East Asian director at ShoreTel, a company that began in 1996 and claims to be the fastest growing PABX vendor in the US and has now decided to expand internationally.

Last month ShoreTel employed three people to establish a sales post here in Sydney, including Martin Trigg, also from Zultys.
