DECT base stations of the M-series (M300, M700, M900) log all activities into an in-memory log. Looking into the phone log is one of the first troubleshooting steps.

In order to log all the information, you need to increase the Syslog level; this can be easily configured through the Web User Interface (WUI):

Set Logs to DEBUG level:

1. Log into the web user interface of the base station.
2. Click on Management menu
3. In the Syslog/SIP Log section set the "Syslog Level" option to Debug

4. Click on Save and Reboot button

In order to obtain the phone log you need to:

1. Log into the web user interface of the base station (WUI).
2. Click on Syslog menu

       3. Click the Clear button

4. Reproduce the issue                                                                                                                                                                                                       

5. Once the error occurs click on the Reload button

6. Copy all the log messages into a .txt file

The internal phone log is stored into a buffer with limited size. In case your issue takes some time to be reproduced, you will need to setup a long term logging via a Syslog server.
