We have an HA ambient on 4.0.3-5.
The client uses Zoiper, and when making calls in some cases the agent only sees the 480 message in Zoiper, of course the agent doesn’t know why. Usually you would hear the busy tone, but this is not the case, the call is ended and the agent is left wondering if he was busy, or if he doesn’t exist.
is any way to open the audio channel prematurely?
What recommendations could you give us?
