[quote=“david55”]They are probably answering the call early, in which case there will be no formal signal. You would need to experiment to see if there was some characteristic sound pattern at the point of answer. Basically, any answer is going to depend on the fine details of their configuration, not just on the behaviour of Asterisk.
If they are reachable by the PSTN, delaying the answer would, typically, result in the PSTN operator dropping the call after a few minutes, which is why I assume that they answer early.[/quote]
Thank you david55 for your prompt reply!
No Actually I plan to place them into my Asterisk Queue after they answer the call. It will be a message played by my Asterisk for them to know that they have to wait and call is in transfer…
All I need to know - how to trigger my Asterisk from the point my call was in their Queue to the point it was answered?
