Gavin,
B B B B B B B B B B If you enableB packet scheduler on the pc you also enable
DSCP .
Default DSCP values can be editedB by using windows B Group Policy.
The network control service cannot be requested through the GQoS API. However,
it can be requested by network management applications that use the traffic
control (TC) API.

Subject: Prioritiesing Voice out of a PC using a soft phone?
Hi GS
I went to the local Cisco Office the other day to verify a unique VoIP
PT design for one of our clients.
To simplify things a call centre is piloting IP Telephony on PC's
ne of the questions the SE asked me was if the PC's are prioritising
he Voice traffic out?
- I can confirm that packets are being marked correctly with CS3 and EF
arkings, but reading further the operating system doesn't appear to
ave any Priority Queue feature?? I have looked at the Windows XP "QoS
acket Scheduler" but this appears to use RSVP and we aren't using this.
Has anyone come across this before?
as anyone had any previous experience with poor performance with Soft
hones because of PC queuing?
ny suggestions on reading material on this issue and ways to overcome
t?
nyone know what the standard FIFO queue depth is for a PC?
NOTE: The pilot is running with 23 users at the moment and the users
ays the voice quality is no better or worse than the TDM solution.
GL
