VOIP Quality

[nnmansoori]

hi, I am running VDI with vSphere 4.1, View 4.0.1, Wyse C10LE, virtual Desktop OS is Windows XP SP3, the clients are call center agents and they use Huawil Softphone, the voice quality is good, but in some hours ( arounf 2:00 pm), the agents claim that their voice quality become bad and the customers cannot hear their voice good, I ran Wireshark and I saw the following result:

Source is my virtual desktop, Destination is my Thin Client, and the message is:

!file:///C:/Users/nastaran.man/AppData/Local/Temp/moz-screenshot-2.png!ICMP : Destination Unreachable (port Unreachable).

I asked the Network guys and they said our connection is LAN is 10GB and we don't have any bandwidth issue.

does anyone know what is this issue for?

Your LAN could be 10Gbe however the host and the virtual machine maybe limited to only 1Gbe. Btw in addition to that could you check out the CPU/Memory/Network perf on the vcenter for the view as well as the desktops. Is there anyway virus scan or backup being run at that time?

I have monitoring on vDesktops and servers by Veeam, vCenter and View is quite free, but vDesktops sometimes have high CPU usage. the VMs network transmit and recieve rate (network usage) is less than 50 KBps.

Hmm, since the wireshark is run against the thin-client could you try another made or model of thin client? if not possible perhaps maybe using a repurpose fat client. The reason of asking is that we faced problem with thinclient which could just perform normally under highload and i was solved with firmware updates.
