Doubt about behavior wait in device (deskphone, IP Communicator or Jabber) with status not register

[wilsonsant]

Hi Guys,

I have the follow doubt: When the external user (PSTN) call a DeskPhone, Jabber or IP Communicator that not is registered, what is the behavior is wait:

1) The User will listen busy tone?

2) The User will listen the message that the number not exist?

3) The User will listen that the phone not is available in the moment?

4) anyway 

If option 2 is correct, are there any configuration to do in the CUCM to blocked this information?

Thanks,

Wilson

Hello,

Its depends what you have configured at your CUCM.

If you dont the forward unregistered configured at the line of your device the caller will hear a busy tone.
