Hi, I'm just observing in the log that user 1001 (and other random users like '55340115419480247') is continuously creating and closing channels. That users doesn't exist (I delete the folder "directory" since I use database with different user names, no numbers). I've done a search some reference to user 1001 in all the configuration and haven't found anything (using "grep -r '1001' /etc/freeswitch/*") Any idea why this happens? A bot or spider maybe?
