Underrun margin time less than defined threshold value
While playing voice data with PlayPrompt, PlayAudioName, PlayGreeting, PlayVoiceMessage, or PlayVoiceSegment, the device driver was close to running out of voice data to play. The accepted threshold value is defined by the system parameters in "Application Server Interface". If the device driver runs out of voice data to play, the system continues to play voice data when more is available, but the caller hears a pause in the voice. Note: This report is based on an average calculated every minute.
This is probably caused by the voice input buffer to the device driver being too small, and is most likely to happen when the system is heavily loaded. Increase the size of the buffer using the Normal Play/Record Max Data system parameter.
