Node type: OBJECT-TYPE
Type: Counter

Range of Values: 0-4, 294, 967, 295
Default Value: none
What is pcmSapTxDesync?
This counter tracks how many silence packets were sent on this channel because the voice application had no real voice data ready to transmit. Admins use it to detect gaps or underruns in the voice application feeding this channel, since a high rate of silence substitution can indicate the upstream voice processing is falling behind. A rising pcmSapTxDesync count during an active call could point to CPU load or buffering issues in the voice application.
