I've a problem with Cisco IP communicator. The communications are of bad quality and sometimes i've absolute silence. I use windows 2000 SP4 or XP SP2 and I use a headset with an adapter USB GN Netcom 8110.

In same time, Lotus Notes and an application JAVA with launch on computer.

An option must be activated or a patch (Cisco or Windows) must be install on the computer or the call manager ?

On my network, i don't have error CRC or input/output error .


P.S. we use Cisco IP Communicator 2.1.1 and Call manager 4.2(3)

I've carry out a capture with wireshark and I see that dscp is egal to 0 thus there is not priority for the voice. I activate QoS on my network card, and on Windows XP SP2, it's ok (dscp = 46) and on Windows 2000 SP4, it's not ok (dscp = 0).

Why ? An option must be activated ?
