This topic explains how to configure audio files for inbound calls and set up a throttling whitelist for outbound calls in the Voice Messaging Service console.
Common inbound call configuration
Log on to the Voice Messaging Service console.
In the left navigation pane, choose General Settings.
Click Call Settings > Common inbound call configuration.
ImportantBefore modifying the global configuration, confirm with your business teams whether inbound calls connect correctly or if a welcome audio prompt is already set. If a prompt is in place, do not enable the global configuration. Enabling global audio file playback routes all inbound calls directly to the audio file, preventing them from reaching your business systems.
Global configuration: Click Modify Global Configuration, set parameters such as configuration type, audio file, and configuration description, and then click Confirm.
Click Add Configuration for Specified Inbound Numbers, and set parameters such as configuration type, qualification type, company, callee number, audio file, and configuration description.
Click Confirm.
Outbound call throttling - frequency
Throttling rules
These rules apply only to voice notifications and voice verification codes.
For the same qualification and purpose, the system limits how often a caller number can call a specific callee number. The limits are 1 call per minute, 5 calls per hour, and 20 calls per 24 hours.
The throttling period begins with the first outbound call. Any calls that exceed these frequencies will trigger throttling. Both successful and failed calls count toward the throttling limit.
NoteThe throttling period begins with the first outbound call. For example, if the first call is at 12:01 and the fifth is at 12:59, a sixth call at 13:00 is throttled for exceeding the hourly limit. The 24-hour limit functions the same way: the count resets 24 hours after the first call.
This limit applies to outbound calls in both public and exclusive mode to protect the callee's experience.
Throttling whitelist application
If you use exclusive mode for outbound voice notifications or voice verification codes, you can apply for a throttling whitelist in the Voice Messaging Service console:
Log on to the Voice Messaging Service console.
In the left navigation pane, choose General Settings.
Click Call Settings > Outbound call throttling - frequency.
Click Apply. Follow the on-screen instructions to complete the application form:
In the Rule field, add a throttling count rule based on your business call frequency.
Once approved, whitelisted numbers for that qualification are exempt from frequency throttling rules. This is for adding test numbers to the whitelist.
Complete the other required fields as prompted on the page.
Click Submit.
Applications are reviewed Monday to Friday, 9:00 to 18:00 (excluding public holidays), and are typically processed within five business days.
