CTS does not auto answer
when the feature is enabled

An incoming conference call is ringing
and the CTS does not auto answer
immediately.

The call is connected but there is no
video.

The CTS rings and auto-answers a call based
on how these features were configured in
Unified CM.

If the call is connected as audio only, check
your IP phone configuration and make sure the
“Disable Speaker/Headset” box is checked.

To disable the IP phone speaker/headset:

1.

Log on to the Cisco Unified CM
Administration interface.

2.

Search for your directory number (DN).
Two devices are displayed: CTS and IP
Phone

3.

Click on the IP_Phone device.

window.

5.

Verify that the following check-boxes are
checked in the Product Specific
Configuration Layout window:
