We have five 7921 phones. There is no problem if you keep using them , but all of them would lock up if you don't use for a while, for example 3 or 4 hours. We see all 7921 phones are dead every morning(beacuse nobody uses them in the evening). When it happens, there is no response at all. We have to pull off the battery to reset phones.
Step 1 On the phone's web page, choose the Trace Settings hyperlink.
Step 2 In the Number of Files field, choose the number of trace files to save, from 2 to 10.
Step 3 In the Remote Syslog Server area, check the box to enable a server to collect the trace files.
Step 4 If you enabled the syslog server, then you must complete these fields:
*IP Address-Enter server IP address
*Port-Enter a port number (514, 1024-65535)
Step 5 In the Module Trace Level area, check only the modules for which you want data:
Step 6 In the Advanced Trace Settings area, in the Preserve Logs field, choose one of the following:
*True-Save the trace logs to flash memory on the phone.
*False-Save the trace logs to RAM.
You can use the Trace Logs area on the web page to view and manage trace files. System trace logs appear in a list on this page. You define how many messages are saved in the Trace Settings area. To view a trace log, click on the "Message.". The trace log appears in ASCII text. You can save the text file in a directory or on a disk to attach it here in the forum for troubleshooting purposes.
