Making and Answering Calls
Making and Answering Calls
The MBU 400 System allows you to make both Internet and landline calls. Landline
calls are calls made over the Public Service Telephone Network (PSTN) just like a
regular phone. All outgoing calls (except emergency calls) are Internet calls by
default, unless you specify otherwise. All emergency calls default to the landline. (If
you don’t have a landline connected, you must change the emergency line setting. See
Changing Emergency Line Settings on page 41 for details.)
The following sections describe how to make and answer Internet, landline, and
intercom calls with the MBU 400 System.
VoIP Calls
To make internet calls on your Aastra MBU 400 phone, you must have registered an
account on the MBU system through either the handset, Web UI, or configuration file.
This may have been done for you by your System Administrator. If there are no VoIP
accounts in the system, you will not be able to make internet calls, and attempts to do
so will result in a red IP icon on the handset display. For more information see
Configuring the Phone Using the Handset on page 23 , the Aastra MBU 400
Administrator Guide , or contact your system administrator.
When you make and receive Internet phone calls, the following icons display:
