To record an IVR greeting sound file:
Once you press 1 your greeting message will be recorded.
Now, every call that comes into this IVR will play your custom greeting message.
Alternatively, you can change or rewrite IVR greeting using these two options:
Change Greeting using greeting access code for specific destination types
Dial *303xxx where xxx is an IVR, Ring Group, Queue, etc. When dialed the user is prompted to record a new greeting. Once accepted, the greeting is set as the destination's new greeting.
Rewrite Greeting using greeting access code for specific destination types
Dial *304xxx where xxx is an IVR, Ring Group, Queue, etc. When dialed the user is prompted to record a new greeting. Once accepted, the greeting is set as the destination's new greeting and the old greeting, if it existed, will be deleted.
