The purpose of capacity limiting is to prevent trunk/peer/interconnect sending too many call requests than given configuration. There are 2 kinds of limiting:
- Call per second (cps) – Max: 50: the amount of calls you can initiate in a single second.
- Concurrent Call – Max: 1000: the total amount of live calls (including calls in calling state) you can have at the same time.
This can help prevent a DOS type attack. If the cps limit is reached, the host will be blocked by software in 60 second. If the Concurrent Call limit is reached, new call will not be processed.
To configure it, please follow the steps below.
