Cisco Unified Communications Manager Express Interaction

Cisco Unified Communications Manager Express Interaction
When the Cisco IP Phone works with the Cisco Unified Communications Manager Express, the phones must
go into CME mode.
When a user invokes the conference feature, the tag allows the phone to use either a local or network hardware
conference bridge.
The Cisco IP Phones do not support the following actions:
Transfer
Conference
Join
Hold
Barge
Direct Transfer
Select
Users cannot create conference and transfer calls across different lines.
Unified CME supports intercom calls, also known as whisper paging. But the page is rejected by the phone
during calls.

External Devices

We recommend that you use good-quality external devices that are shielded against unwanted radio frequency
(RF) and audio frequency (AF) signals. External devices include headsets, cables, and connectors.
Depending on the quality of these devices and their proximity to other devices, such as mobile phones or
two-way radios, some audio noise may still occur. In these cases, we recommend that you take one or more
of these actions:
• Move the external device away from the source of the RF or AF signals.
• Route the external device cables away from the source of the RF or AF signals.
• Use shielded cables for the external device, or use cables with a better shield and connector.
• Shorten the length of the external device cable.
