Full deployment of Teams voices for HKU staff
As previously noted in the University-wide Teams Voice Adoption initiative, now HKU staff telephone services have been integrated under the Microsoft Teams platform except for office spaces at the Hong Kong Jockey Club Building for Interdisciplinary Research (JCBIR), Cyberport 4 (CP4) and the Prince Philip Dental Hospital (PPDH). This transition offers enhanced communication features, including chat, voice and video conferencing, and phone calls for eligible full-time staff. Furthermore, Teams is seamlessly integrated with Microsoft 365, providing robust file collaboration capabilities that help to improve overall productivity. From now on, all new HKU phone deployments, including those at JCBIR, CP4 and PPDH, will use the Teams voice platform.
