Understanding QoS Modifications
Cisco IP Communicator Administration Guide for Cisco CallManager
1-12
If the device was added to the database individually, using
•
Cisco CallManager Administration, or in bulk, using the Bulk Administration
Tool (BAT), Cisco CallManager identifies the device. (This is only true if
you are not using BAT in conjunction with the Tool for Auto-Registered
Phones Support, otherwise known as TAPS).
Otherwise, the device attempts to register itself in the Cisco CallManager
•
database (when auto-registration is turned on in Cisco CallManager).

Voice quality can be compromised on an IP device by data traffic. Because
Cisco IP Communicator is a software-based phone instead of a hardware phone,
you cannot solve this problem by isolating Voice-over-IP traffic to an auxiliary
VLAN. Instead, you must modify Quality of Service (QoS) parameters in the
network so that voice data traffic is prioritized over generic data traffic.
For more information about configuring QoS in your network, refer to the
Cisco AVVID Network Infrastructure Enterprise Quality of Service Design guide
and other network design guides, accessible from this index:
