This issue is documented in Cisco bug ID CSCdy33907 and resolved in SoftPhone Interim build 1.3(2.4) and later.

This problem has been noted only when the call is made with the G.729 codec. A workaround to this problem is to use G.711.

CSCdy33907 does not appear to apply to the problem described.

Poster is using IP communicator 2.0, not softphone 1.3

He did not mentioned of being using G.729

CSCdy33907 is not even visible in Bug toolkit.

Thanks for helping I made a test with another dsp 400 that was acquired 1 year ago and the noise doesn?t exist in this one so I think that the news dsps 400 are failing so, We must replace them.
