H.323 Clients and CTI Ports
Cisco CallManager Administration enables you to configure software-based
devices such as H.323 clients and CTI ports. Software-based Cisco CallManager
applications such as Cisco SoftPhone, Cisco AutoAttendant, and Cisco IP
Interactive Voice Response (IVR) use CTI ports that are virtual devices.
H.323 clients include Microsoft NetMeeting devices.
You configure H.323 clients and CTI ports through the Phone Configuration
window in Cisco CallManager Administration like you do phones, but they often
require fewer configuration settings.
Note Cisco recommends that you do not configure CTI ports or devices that use TAPI
applications in a line group.
For information on H.323 clients and shared line appearances, see the “Shared
Line Appearance” section on page 40-26.
