When enabled, the password will not be stored in flash, but only in memory after entering manually after each power on sequence for seamless roaming. However, the username can be stored after entering at the prompt, but can be overridden at the next login. If the prompt is dismissed, then there is a “Login” softkey presented in order to invoke the login process. The Prompt Mode feat

• Cisco 7925G - Unified Wireless IP Phone VoIP, Cisco Unified Wireless IP Phone 7925G Deployment Guide 20 Quality of Service (QoS) Quality of Service enables queuing to ensure high priority for voice traffic. To implement appropriate queuing for voice traffic, use the following suggestions: • Ensure that WMM is enabled on the access point. • Create a QoS policy on the access point giving priority to voice (RTP) traffic and apply that profile to the desired interfaces.  RTP (DSCP = EF) to COS = 6  SCCP (DSCP = CS3) to COS = 4 • Be sure that RTP packets have the proper QoS markings and other protocols are not using the same QoS markings. • Select the “Platinum” QoS p

Restricted Data Rates The restricted data rates feature utilizes the Traffic Stream Rate Set (TSRS) information element from CCX v4, which can define a data range (upper and lower) for the client to use (i.e. 12 - 24 Mbps). This can be beneficial for environments that have legacy clients requiring lower data rates to be enabled on the access point, but also preventing other clients from down

Set only the lowest data rate enabled as the single basic rate. Multicast packets will be sent at the highest basic data rate enabled. Note that capacity and throughput are reduced when lower rates are enabled. If Call Admission Control (TSPEC) is enabled then the Traffic Stream Rate Set (TSRS) feature will also be enabled, which will allow lower rates to be enabled for legacy devices, but prevent the C
