this is what Unity is supposed to do... when the call forwards into Unity from an extension number, we look that extension up, find the mailbox in this case and we will deliberately skip the transfer rules in this case and go straight to the greeting. You can imagine if we didn't do this we could very easily get caught in a "transfer loop" where we send the call out, it comes back in busy/RNA which would then forward back out to the extension etc... until we ran out of ports and the call was dropped. not good.
You essentially want to provide holding services without using the switch to do it here... call forwards into Unity busy you want us to immediately tell the person they are on hold and there are x people in front of them... is this right? There are probably better ways to go about this using functionality external to Unity but here’s one way you can handle it.
Enable the busy greeting for this person’s mailbox… set it to “blank” greeting and in the after greeting action set it to “attempt transfer for” the same mailbox. This “loop around” trick will take all calls that forward busy to this mailbox and try the number again… which will then put them in the busy queue you’re looking for.
This is a real good way to chew up a lot of ports in a hurry so be careful… but that should work for you.
