Cisco Unified Wireless IP Phone 7921G Administration Guide for Cisco Unified Communications Manager Release 7.0

OL-15985-01

Chapter 2      Overview of the VoIP Wireless Network

Components of the VoIP Wireless Network

Unlike wired networks with dedicated bandwidths, wireless LANs have to consider traffic direction 
when implementing QoS. Traffic is classified as upstream or downstream from the point of view of the 
AP as shown in 

Figure 2-2

.

Figure 2-2

Voice Traffic in a Wireless Network

Beginning with Cisco IOS release 12.2(11)JA, Cisco Aironet APs support the contention-based channel 
access mechanism called Enhanced Distributed Coordination Function (EDCF). The EDCF-type of QoS 
has up to eight queues for downstream (toward the 802.11b/g clients) QoS. You can allocate the queues 
based on these options:

  •

QoS or Differentiated Services Code Point (DSCP) settings for the packets

  •

Layer 2 or Layer 3 access lists

  •

VLANs for specific traffic

  •

Dynamic registration of devices 

Although you can have up to eight queues on the AP, you should use only two queues for voice traffic 
to ensure the best possible voice QoS. Place voice (RTP) and signaling (SCCP) traffic in the highest 
priority queue, and place data traffic in a best-effort queue.Although 802.11b/g EDCF does not 
guarantee that voice traffic is protected from data traffic, you should get the best statistical results by 
using this queuing model.

Note

The Cisco Unified Wireless IP Phone 7921G marks the SCCP signaling packets with a DSCP 
value of 24 and RTP packets with DSCP value of 46.

To improve reliability of voice transmissions in a nondeterministic environment, the Cisco Unified 
Wireless IP Phone 7921G supports the IEEE 802.11e industry standard and is Wi-Fi Multimedia 
(WMM) capable. WMM enables differentiated services for voice, video, best effort data and other 
traffic. However, in order for these differentiated services to provide sufficient QoS for voice packets, 
only a certain amount of voice bandwidth can be serviced or admitted on a channel at one time. If the 
network can handle “N” voice calls with reserved bandwidth, when the amount of voice traffic is 
increased beyond this limit, (to N+1 calls), the quality of all calls suffers.

To help address the problems of VoIP stability and roaming, an initial Call Admission Control (CAC) 
scheme is required. With CAC, QoS is maintained in a network overload scenario by ensuring that the 
number of active voice calls does not exceed the configured limits on the AP. The Cisco Unified 
Wireless IP Phone 7921G can integrate layer 2 TSpec admission control with layer 3 Cisco Unified 
Communications Manager admission control (RSVP). During times of network congestion, calling or 
called parties receive a fast busy indication. The system maintains a small bandwidth reserve so wireless 
phone clients can roam into a neighboring AP (AP), even when the AP is at “full capacity”. After 
reaching the voice bandwidth limit, the next call is load-balanced to a neighboring AP without affecting 
the quality of the existing calls on the channel.
