EBS: What Is Broadcast Throttling in Everbridge Suite and How Can the Broadcast Duration Be Adjusted for Broadcast Throttling



What is broadcast throttling and how to adjust the broadcast duration for broadcast throttling.


Broadcast throttling slows the rate of processed voice calls to match what the receiving system can handle.

For example, a notification might place 200 calls to an office that can only handle 125 calls at a time. Everbridge will try to deliver the message as quickly as possible, but due to the office's 125 call limit, 75 calls would be dropped, and those 75 contacts would receive the notification through their next contact method.

Had broadcast throttling been used in this instance with a maximum of 100 simultaneous calls set, only 100 calls would be active at a time. Broadcast throttling provides control so that when one of the active 100 calls finishes, only one other call will become active.

The following formula can be used to determine how long a given broadcast might need to complete:

Throttling Equation

Using this equation, if a total of 2000 calls each lasting two minutes needed to be placed to a receiving system that could only handle 40 calls at a time, the broadcast would need at least 100 minutes to complete. The notification's broadcast duration would need to be set to at least two hours.

To set a broadcast throttling rule, follow these steps:

  1. Log in to the Manager Portal and select the appropriate organization from the upper right-hand corner.
  2. Select Settings from the top menu bar.
  3. Select Notifications from the menu on the left.
  4. Select Broadcast Throttling from the sub-menu.
  5. Set the desired Preferences by checking the corresponding check boxes and choosing Save.
  6. Create a Rule Name and choose the Country that the rule will apply to.
  7. Enter the Throttling Pattern. The throttling pattern is set by entering the area code or codes and prefixes of the numbers to be dialed during a broadcast. The rules for a throttling pattern are as follows:
    1. It must be at least three digits long.
    2. Do not separate multiple area codes and prefixes.
    3. Up to six area codes with their prefixes can be entered for a throttling rule's pattern.
  8. Enter the Max Simultaneous Calls the throttling rule will allow if desired.
    1. If no value is entered, the default will be no limit.
  9. Choose Add.

Added throttling rules can be edited by selecting Pencil Icon and deleted by selecting Trashcan Icon.
