I have a fresh install of Freepbx 22.214.171.124 and Asterisk 13.19.1. For some reason it has a ton of upload bandwidth usage and seems to essentially DDOS my network – in the last 24 hours it uploaded 128gb of data but only downloaded 10.1mb.
I use Twilio as my SIP trunk, which is on port 5060. The server log shows a lot of random bots trying to brute force an extension registration, but I have anonymous registration turned off so they are being denied. It doesn’t always seem to correlate with when Freepbx uploads large amounts of data however. Is it still perhaps related or is something else the issue?
