[cisco-voip] talking normally then way fast

[Norton, Mike]

In my non-work life I pretend to do some audio stuff, and I have seen symptoms like that when the soundcard can't decide what sample rate it's supposed to run at. For example, if the driver wants to force to the hardware to a particular sample rate, but a device connected to the optical input is providing clocking at a different rate. Or if multiple applications are trying to control the sample rate instead of letting the driver convert their signals to something common.

I would try to confirm whether it is a soundcard issue or a network traffic issue before wandering too deeply down either troubleshooting path.

This has got us stumped.

CM 4.2 and Softphone user from home over VPN.

User calls because she is having soft phone issues.  Leave us a VM.  for about 25 seconds the vm is normal speed.  Then the last few seconds are condensed into 1 sec.

Call her back.  Real time audio has some of the same issues.  Talking fine, then dead air and then a super fast talk.

Seems like maybe there is some kind of software on her box that is storing and forwarding packets.  Anyone else ever see this?

I would be happy to forward off line to hear it.  We are idealess.

Thanks

Scott
