IVR: Intermittently, when prompts play in callflow, no audio is heard, or messages are cut off

PROBLEM

Intermittently, when prompts play in callflow, no audio is heard, or messages are cut off before completion.

SYMPTOMS

The device logs indicate that the prompt is playing without errors, but no audio is heard, or audio is cut off before the prompt has finished playing. Restarting the related service may resolve the issue temporarily, but it will recur.

WORKAROUND

For prompts not playing, add a Delay activity of 1 or 2 seconds just after the Answer activity; for prompts being cut off before completion, add a Delay activity of 1 or 2 seconds just before the Hang Up activity.
