While I appreciate trying to please the customer, this request has too little merit to be considered:
1. If there is silence when the agent answers a call, the customer would just hang up.
2. Since the agent obviously cannot talk to 2 people at the same time, why aren't they changing their status to Off-queue so they don't get the call?
3. If the vendor calls are so important, why can't they dial out through Genesys Cloud so it won't give them a call and that call can be recorded and accounted for.
