Click-To-Talk Group
16.1 Overview
This chapter shows you how to configure Click-To-Talk (CTT) groups to answer
calls sent over the Internet with a web-based IP phone.
The CTT feature allows you to place a specially created HTML link on a Web page
which a user can then click to connect directly to a live extension on the other
end. This communication uses the SIP voice protocol with a web-based IP phone
client handling the connection on the caller’s side and the X6004 routing the
connection to the recipient’s phone on the other.
Figure 126 A Click-To-Talk Example
For example, when a user A clicks on an embedded Click-To-Talk link on a
company’s online ordering web page, the web-based IP phone opens. Next, the
phone dials into X6004 B, which in turn routes the call to extension C. Both A and
C can then talk to one another over the Internet as if they were talking by an
actual phone. (The web phone only works if the caller’s web browser supports it
and they have a functional microphone attached to their computer.)
