What is pcmSapRxBusy?

This counter tracks how many times the receiver FIFO buffer for this channel became full. Admins use it to detect that incoming voice data is arriving faster than it can be processed, which can cause audio quality problems like clipping or dropped frames. A rapidly increasing pcmSapRxBusy count would prompt an admin to investigate processing load or buffer sizing on that link.

Examples
