what will happened during the Dial or it rings to the agent, now the caller will put down the phone or end the call. but it happened it will continue to ring in the side of agent, it keeps ringing even the customer puts down the phone or end up the phone.
You need to provide information on how the caller is reaching the system. For example, is it connected using SIP, is it from the PSTN, is it from an analog telephone line?
He told me that he use the follow me option ? when dialplan Dial the local 5000 this will ring to all agents that he sets…my problem is that even the customer hangup the call but it continues to ring…what probably the limitation for this so that I will inform my colleague.
If it’s because of the technology, for example using an analog telephone line, then not really - you’d need to change. Asterisk can only do as it is told - so if it’s not being told they hung up, not much it can do.
Switching to a VoIP provider would work, but without actual details about what technology is being used right now these are only guesses. You would need to provide more information for anything further.
