Troubleshooting Your SoundPoint IP / SoundStation IP Phones

Log Files

SoundPoint IP and SoundStation IP phones will log various events to files

stored in the flash file system and will periodically upload these log files to the

boot server. The files are stored in the phone’s home directory or a

user-configurable directory.
There is one log file for the bootROM and one for the application. When a

phone uploads its log files, they are saved on the boot server with the MAC

address of the phone prepended to the file name. For example,

00f4f200360b-boot.log and 00f4f200360b-app.log are the files associated with

MAC address 00f4f200360b. The bootROM log file is uploaded to the boot

server after every reboot. The application log file is uploaded periodically or

when the local copy reaches a predetermined size.
Both log files can be uploaded on demand using a multiple key combination

described in

. The phone uploads

four files, namely, mac-boot.log, app-boot.log, mac-now-boot.log, and

mac-now-app.log. The “now_” logs are uploaded manually.
The amount of logging that the phone performs can be tuned for the

application to provide more or less detail on specific components of the

phone’s software. For example, if you are troubleshooting a SIP signaling

issue, you are not likely interested in DSP events. Logging levels are adjusted

in the configuration files or via the web interface. You should not modify the

default logging levels unless directed to by Polycom Technical Support.

Inappropriate logging levels can cause performance issues on the phone.
In addition to logging events, the phone can be configured to automatically

execute command-line instructions at specified intervals that output run-time

information such as memory utilization, task status, or network buffer

contents to the log file. These techniques should only be used in consultation

with Polycom Technical Support.

Application Logging Options

Each of the components of the application software is capable of logging

events of different severity. This allows you to capture lower severity events

in one part of the application, while still only getting high severity event for

other components.
The parameters for log level settings are found in the sip.cfg configuration file.

They are log.level.change.module_name. Log levels range from 1 to 6 (1 for

the most detailed logging, 6 for critical errors only). There are currently 27

different log levels that can be adjusted to assist with the investigation of

different problems.
When testing is complete, remember to return all logging levels to the default

value of 4.
