Error and Status Messages
Note:
This section describes error and status messages only for those IP telephones having a display. For error and status messages related to installing a 4601 IP Telephone, see Troubleshooting the 4601 IP Telephone on page 92.
The 4600 Series IP Telephones issue messages in English only. The IP telephones also display messages from the switch, which can issue messages in the local language outside the United States.
Most of the messages in Table 3 display only for about 30 seconds, and then the telephone resets. The most common exception is Extension in Use, which requires manual intervention.
