In-Depth Information
There are three different types of CTI control devices:
■
CTI ports:
These virtual devices allow the creation of virtual lines.
■
CTI route points:
These can receive many calls simultaneously for application-controlled redirection. They support
numerous features, including answering calls, redirecting calls, holding calls, and dropping calls. Calls can be redirected to a
CTI port or IP phone.
■
Cisco IP phones:
A CTI application can control these phones.
CTI ports and route points are used by applications including Cisco Softphone, Cisco IP Interactive Voice Response (IVR), and Cisco
Auto-Attendant. If a CTI device fails, media streams for calls that are already set up may be preserved, while calls that are in the
process of being set up or modified are dropped.
