3.5.3 The number of calls

In some circumstances, you may wish to restrict how often a number can be dialled, this is usually required for credit control reasons, but could also be used if, for example, an advertiser has paid to receive a certain number of calls.

Example

We are creating a new overlay, but we only want the number to be called 100 times.

• Specify that the call can only be called 100 times: maximumConnections=100

Note, if you call numberOverlay again for the same reference string you will reset this count!
