Hi GS
I went to the local Cisco Office the other day to verify a unique VoIP
IPT design for one of our clients.
To simplify things a call centre is piloting IP Telephony on PC's
One of the questions the SE asked me was if the PC's are prioritising
the Voice traffic out?
- I can confirm that packets are being marked correctly with CS3 and EF
markings, but reading further the operating system doesn't appear to
have any Priority Queue feature?? I have looked at the Windows XP "QoS
Packet Scheduler" but this appears to use RSVP and we aren't using this.
Has anyone come across this before?
Has anyone had any previous experience with poor performance with Soft
phones because of PC queuing?
Any suggestions on reading material on this issue and ways to overcome
it?
Anyone 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
says the voice quality is no better or worse than the TDM solution.
GL
