Reject
Reject
The <Reject> verb rejects an incoming call to your CPaaS endpoint and can be used for blocking unwanted calls. If the first verb in a RCML response is <Reject>, CPaaS will not pick up the call. The call ends with ‘busy', 'no-answer' or other status, depending on the verb’s 'reason' attribute. Any verbs after <Reject> are ignored and won’t be executed.
