Noise in conferences between different Regions

When we stablish a conference where one of the participants is in another region (so it has to speak G729)after around 2 minutes of conference the person of the other region hears a lot of noise during 10 s. We have checked it is not a problem of QoS.

We have for each site a transcoder defined and we have only one resource for conference placed in the Call Manager in the central site.

Do you know the reason?

I think you may be running to bug CSCdv51384

Are you using the PVDM2 modules in a 2800 or 3800 series router for conferencing? I would upgrade to the latest release of 12.3(14)T software, earlier versions had problems with noise when transcoding and conferencing.
