Design Help

[admin_2]

Here is my situation. In a High School environment I HAD most teachers assigned to a room extension, and made their VM extension the same, the few that had no room, just had a VM extension. <br><br>No the principal does NOT want the phone to forward to VM and wants the classrooms to have a seperate extension from the teachers VM extension. So I know that I can assign a seperate extension to the Staff, so how should I set this up? Just have the phones forward to a Call Handler when busy/NA then allow the caller to select by extension or last name, (which to me does not buy anything) or how can I allow the room phone to ring so many times before going to VM (Other than the setting in CCM), can I use supervised transfers, etc etc etc...does anyone have a decent flowchart or documentation for a set up like this?<br><br> Thank - Mike<br><br>------------------------------<br>Michael Perbix<br>Lower Merion School District<br>Telecommunicatons Specialist

You can setup phones with dummy MAC addresses and have them CFA to the Unity system. Then if somebody calls one of the extensions they will get the teachers voicemail.

If you then want them to be able to transfer to the classroom you can setup a supervised transfer to the class room phone number with the 'Yes, ring subscriber at this number:' menu. Make sure to set the 'rings to wait' to less than the CFNA timer in the CallManager.

Are you sure Keith?

My understanding of Unity is, that all calls that are forwarded by the CallManager can´t use the "supervised transfer" feature on Unity.

If you try this way, you will see that calls forwarded by the CallManager (CFA, CFB, CFNA for the line) always are connected directly to the subscribers mailbox.
There is no reaction on Unitys "supervised transfer" configuration for the subscriber.

If you know a way to do this, I would be happy to know that.

I think it should be able to supervise transfer to another number but I will need to test it. I'm in Seattle on vacation now but I will test it as soon as I get back to San Jose and let you know.

Unity can supervise transfer to a phone that is forwarded in a no-answer condition as long as the number of rings the CallManager will forward on no-answer is higher than the number of rings Unity will wait. If call foward all is set on the phone, then supervised transfer technically still works, it's just that the phone will never ring, and you'll go straight to the subscriber's greeting.

If you are experiencing specific problems with Unity supervise transfers to phones that are forwarded in no-answer conditions, let us know what they are. We'll be able to help out.

On another note, with the CallManager integration, supervise transferring to a forwarded busy phone (when the phone is in a busy condition) appears to work, but I doubt the QA folks here bang around on such a test plan. With legacy PBXs this is a great big no-no. With legacy PBXs, having two parties try to control that call at the same time will cause really weird stuff to happen.

Hi Steve,

do you really have test it?

I´m using Unity 4.6.135 (german), CallManager 3.1(2c) and AV-TSP 3.0.2.

In all my configured conditions was no chance to get an supervised or released transfer for CallManager extensions wich were forwarded on busy or no answer (frustrating: always the subscribers greeting with the option to leave a message was to hear).

Only if I use direct (no CallManager forwarded) calls to Unity in a dial-peer from the router to the IP of Unity was it possible to get supervised or released transfers to CallManager extensions.

But in that design we have always the rule of the opening greeting where the caller have to pass through. There is no way to bypass this.(?) The calling (e.g. from PSTN) user wouldn´t like to dial the extension of the called IP-extension a second time (extension dialing on opening greeting) if he dialed the complete number of the subscriber already. Even though we would like to use the feature to supervise if the subscriber is busy.

I hope you understand my problem and the design I like to have to. (PSTN call -> Router -> CCM-extension: forward busy -> Unity -> subscribers supervised transfer for his busy or no answering extension)

regarding the subscriber rights:
There are no restriction tables that disallows call transfers for the specific subscriber.

I hope you can help me.

Usually you would use subscriber boxes for Staff extensions and Call Handlers for Room extensions. You would likely set the message recipient for the room handler to the associated teacher or a distribution list.

If you use supervised transfer for the room extensions, and disable any forwarding on those extensions in the phone system, you can set the number of rings Unity will wait before pulling the call back to the call handler.

The administration guide has information about planning and programming subscribers and call handlers.

If you need to change all of the teachers extensions, you can use the bulk edit tool on the www.answermonkey.net web site.
