<p>Hi All,</p><div> </div><div>I am testing QoS for CIPC and in general planning to deploy in a big enviornment.</div><div> </div><div>I have few questions.</div><div> </div><div>1) First one is on QoS</div><div> </div><div>
The enviornment is already QoS enabled and will classify the voice and signalling traffic at router level. However at Catalyst switches auto qos is enable for cisco phones (desk). Whats the best approach for QoS at switch level. </div>
<div>There are two auto qos options one for cisco-phones and other for softphones but we already have the one for cisco-phones enabled. So to configure the port facing PC+Desk Phone + Soft phone, I was looking at SRND and testing untrsuted PC + soft phone + scavenger model. Is this the right approach?</div>
<div> </div><div>Also according to the SRND the Voice class is policed at 128K - is this right? I know this is per port but policing at 128K is this right approach?<font size="1" face="Courier"><font size="1" face="Courier"><p align="LEFT">

<div> </div><div>2) Running soft phones on Wireless - things we need to take care of?</div><div> </div><div>3) Any other general recommendations or things to be aware of while rolling out softphones in a big enviornment. </div>
<div>Bandwidth used will depend on codec used and will be in line with the BW usage by normal phones i believe as per config in CUCM. </div><div>Licenses i am thinking of using adjunct option by configuring primary extension as desk phone (so that it uses one DLU).</div>
<div>Data vlan will have tftp option for soft phones in dhcp.</div><div> </div><div>Thanks.</div><div> </div>
