Which setting in Asterisk is responsible for the dial tone?

Question

Asterisk

Comrades!
Such situation. When making local calls among themselves, sometimes a situation occurs that the person who is being called has already picked up the phone and answered, but the caller hears beeps for another 1-2 seconds, together with the fact that he already hears the answerer. those. beeps are superimposed on top. The feeling that the system just needs to complete the beep, so it does not stop it when the handset is removed.
How can this be corrected?

Answer 1

In IP telephony, ringing and beeps are usually generated by the telephone itself. Asterisk in the SIP protocol simply sends a Ringing message to the phone.

Answer 2

Although the devices generate "beeps", your problem is not related to this. The device settings will not help you here.
Pay attention to call-flow in such problematic calls, as a rule, the problem with continuing ringing after hanging up is connected to the network. In some place, an ACK from your device does not arrive in time to one of the devices, saying that you picked up the phone.
Dump such a call and look at the time and order of all messages.
