Sound of call making and receiving at the same time

Hi,

After we notice this issue:

We would like to see some behavior with calls improved.

If one of the queues that is associated with extension 100, receives a call, while the extension makes a call and waits for the recipient of the call to answer, (Ex: 100 → 999 or 100 → 999999999), it starts to hear the signal of the two simultaneous calls, the one being made by extension 100 and later the queue entry.
We suggest that only be notified with an alert in the application for the incoming call when you we making a call so as not to hear the sound of the outgoing and incoming calls at the same time.
