I get a message «Unable to start V*MOTE» just after having changed the IP address in V*MOTE Config – what can I do?

Wait a few seconds for the service to restart, then try again!

My status LED has turned red even though the measured values seem to be okay (CPU, jitter, loss). What happened?

The CPU value displayed being an instantaneous one, it is probable that this value has temporarily passed the threshold of 80%.
To refresh the LED display, click onto it.

I encounter drop-outs in my audio streams that I cannot explain, where do they come from?

Your computer probably runs a device driver that does not conform to DPC routine management specifications.
We suggest to check whether this is the case for your computer.
A tool you might use is, e.g., DPCLAT (DPC Latency Checker). For more information please refer to www.thesycon.de/eng/latency_check.shtml.

I have launched V*MOTE and I’m connected to a participant, but I don’t see neither the OnAir nor the Talk button. Anything wrong?

Everything is fine on your V*MOTE side; there are two explanations:

  • the participant’s codec IS NOT an IQOYA codec
  • the participant’s codec IS an IQOYA codec, but the OnAir/Talk features have not been enabled

  • V*MOTE - and V*MOTE Config - take ages at start-up; the system seems to be busy, what is it doing?

    There are two possible reasons for this behaviour:

    1. You have installed and been using V*MOTE with an evaluation license, and this temporary license has now expired.

    To check whether this is the case, launch


    to check the license validity.

    2. V*MOTE is an application based on Microsoft WPF that accesses ‘http://crl.microsoft.com’. In case your http proxy is poorly configured, the application may need more than a minute before it is up and running. crl.microsoft.com is Microsoft’s certificate authority server (CRL stands for «Certificate Revocation List»), used to verify whether the certificate for an application (or website) is legitimate or not.

    You can either configure your http proxy through V*MOTE Config to ensure fast access to the above-mentioned Microsoft web site, or you can workaround and prevent your applications – all of your applications! – to connect to the corresponding Microsoft server. To do so,

    go to IE, select Tools|Internet Options|Advanced

    Uncheck “Check publisher’s certificate revocation” on the security tab.
