IP Telephony Configuration Guide
After you have entered all the configuration information, the telephone attempts to connect to the
Business Communications Manager. The message
Locating Server appears on the display. If
the connection is successful, the message changes to
Connecting to Server after about 15
seconds. Initialization may take several minutes. Do not disturb the telephone during this time.
When the telephone connects to the server and is ready to use, the display shows the time and date.
As well, the six keys at the top of the display are labelled.
If you experience problems with IP telephone registration, refer to the section: “Troubleshooting
IP telephones”.
Notes:
• If the DN record has not yet been configured, as will be the case with auto-assigned DNs, you
will only be able to make local calls, until other lines have been assigned in the DN record.
• If the telephone has not been registered before, you will receive a New Set message. Enter the
information, as prompted. Refer to “Registering the telephone to the system” on page 48.
Troubleshooting IP telephones
If the system is not properly configured, several messages can appear.
Programming note: To see the configuration information for a telephone connected to the
Business Communications Manager: When the telephone is not on a call, press the key
(bottom-right corner of the telephone), followed by the key (next to the key).
The display will automatically scroll through the configuration settings.
