Cool. Thanks for that option.

I am not very familiar with Unity connection but I am sure that the below steps are valid: 

Create a call routing rule for forwarded calls...matching on the calling number to be the range of the unity ports (which is a loop as this would be a call that unity initiated and come back to it) then the result of this call routing rule is to send the call to goodbye greeting which plays goodbye and then hangs...you could even customize one without playing the greeting. 

Hope this help.

After enabling the call loop detection using DTMF it worked. I'm going to open a TAC case to ask why the other option did not work to see if it's working by design, a bug or a documentation issue.

Actually, looks like they use something different. 


Call Loop Detection by Using DTMF Enable for Supervised Transfers 
Enable for Forwarded Message Notification Calls (by Using DTMF) 
DTMF Tone To Use 
Guard Time milliseconds 
Call Loop Detection by Using Extension Enable for Forwarded Message Notification Calls (by Using Extension) 

Under phone system basics. 

I'll have to test that out later. The Call Loop Detection by Using Extension is already enabled, but it's not working.

Now that you say that, I recall someone mentioning that before. 

I'm more interested in Unity Connection right now, when I go to the port listing, I see an extension column which is blank, but when I go to edit, I can't add the extension anywhere. 

Perhaps it's a bug.

For Unity do you have the DNs configured on the vm ports in UTIM? I believe this was supposed to be used to prevent loops. Not sure how connection comes into play, it's been a long time since I worked on Unity.

OK - I know this is going to be a silly question, but I just know it's gonna happen. 

I just tested enabling my own extension as my notification device, and lo and behold, the system calls me when a message is left, and then leaves a message when I don't answer, and starts the cycle all over again. 

Is there a way to prevent this? You'd think that it would check to see that the extension or any of the alternate extensions are not added as a notification device. 

This could quickly bring the system down.
