What is the Asterisk Feature Name or what is the feature call: when a user is on a call for a certain period and then an audio signal notifies them.
Example: If an call center agent is on a call for 10 minutes then the pabx will play a beep sound to notify them that they are on the call for 10 minutes.
What you want to happen after that?
Dial() has build-in feature to play something when X ms are reached as a warning and drop the call (or repeat that warning after Y ms).
Just to answer the question in the response. Once the call is on for 3 minutes I want the call the continue but it is just as a reminder or notification for the agent.
