Telephony Services (IP Phones)

CityUHK telephony services (aka IP Phone) utilise Voice over Internet Protocol (VoIP) that allows voice and video calls to be conducted over a private IP network.  VoIP allows not only voice, but also data and video to be transmitted over IT network cable or Wi-Fi network.  Below listed some advantages of IP Phone:

• Corporate phone book is integrated into the IP Phone.
• IP Phone can be relocated to anywhere on the network without reconfiguration
• Telephone number is associated with the IP phone but not a specific location
• Line settings can be managed via a web-based configuration interface
• Cabling is shared with the data network
• IP Phone is available in wired, wireless, or soft phone (via Microsoft Teams) format.
