We are planing a deployment of 50 spa525g2 phones connected only on wifi. In terms of wifi qos, are these devices certified Cisco ccx ?

Hi,
Not sure if you are asking about using SPA phone for Cisco UCCX deployment. But SPA phone are not certified to work with Cisco UCCX.

Hi,
When speaking ccx for wifi and qos CCX means Cisco Compatible Extensions

Phillipe,
This is hard to find.
From the data sheet
The WI-FI client
Wi-Fi | 802.11b/g, Wi-Fi Multimedia (WMM) (802.11e) |
WMM 802.11E
This SPEC
From
http://www.cisco.com/en/US/docs/wireless/bridge/1400/12.3_8_JA/configuration/guide/p38.pdf
Impact of QoS on a Wireless LAN
•
•
The Ethernet downstream flow is traffic sent from a switch or a router to the Ethernet port on the
bridge. If QoS is enabled on the switch or router, the switch or router might prioritize and rate-limit
traffic to the bridge.
The radio downstream flow is traffic transmitted out the bridge radio to another bridge. This traffic
is the main focus for QoS on a wireless LAN.
=========================
So from all this I think you have to take it that the phone supports WLAN QOS as it supports 802.11E.
As far as the CCX programme is involved this is for certifying NON Cisco products.
They won't CCX their own kit but they might CCX a POLYCOM for example
Hope this helps
Wireless LAN QoS features are a subset of the proposed 802.11e draft. QoS on wireless LANs provides
prioritization of traffic from the bridge over the WLAN based on traffic classification.
Just as in other media, you might not notice the effects of QoS on a lightly loaded wireless LAN. The
benefits of QoS become more obvious as the load on the wireless LAN increases, keeping the latency,
jitter, and loss for selected traffic types within an acceptable range.
QoS on the wireless LAN focuses on downstream prioritization from the bridge. These are the effects of
QoS on bridge traffic:
