If you found some error in WCS operation and this error can be reliably reproduced on your server, you can prepare an error report as described below:

Collect debug logs

1. Enable logging of debug information by adding to the /usr/local/FlashphonerWebCallServer/conf/flashphoner.properties settings file this line:

client_log_level=DEBUG

2. Restart WCS with the command:

service webcallserver restart

3. Run traffic pcap-dump using the command

tcpdump -i any -s 4096 -w log.pcap

4. Reproduce the error you experience

5. Stop traffic dumping by pressing Ctrl+C in the window of the temrinal where tcpdump was started.

6. Find debug logs. To do this:

6.1 Go to the location of the today's logs, for example

cd /usr/local/FlashphonerWebCallServer/logs/client_logs/2018-04-19

6.2 List all logs to the screen and sort by the modified date

ls -lt

Sample result:
