|
|
Hello, Throwing calls from Asterisk to PSTN (via a VoIP gateway) some operators sends an explaining audio, in situations as: The phone number does is not assigned The phone is powered off etc. The audio is sent before the call to be answered. So, in an automatic dialling application I'd like to recognize that audio to know what to do with those calls (queue them to a service, mark as wrong number, unavailable, etc.). Does Asterisk have any functionality to recognize the audio in early media (similar to the answer machine detection)? Is there a way to record the audio in early media to implement my own early media detector? Thank you in advance
