Performance management solutions provider, Integrated Research (ASX:IRI), has announced three appointments in the VoIP area. Nathan Brumby has been appointed general manager, IP Telephony, following his departure from the role of chief process officer for software development firm Object Consulting. Brumby was previously CEO of Software Engineering Australia, the initially Government funded software certification body, which was taken over by Object Consulting after failing to make the transition into a viable standalone business. Stephen Sarjeant, the new regional manager for Asia/Pacific, the Middle East, and Africa, has been part of Cisco Systems and its channel family for most of his recent work experience in the UK, Middle East and Australia. He joins Integrated Research directly following a consulting assignment with Dimension Data, prior to which he was New South Wales branch manager with Cisco Systems. Kailem Anderson, IP telephony relationship manager, Denver, US, will relocate to Denver as a result of the success and expansion he has created for Integrated Research's Prognosis IP telephony product.
