    MORE INFORMATION IN EVENTS LOGS

    Many clients ask for more detailed event information such as an IP added to the blacklist. Know which user tried to login, etc. Right now only the IP is known, but there is no information about the user / extension that tried to login.

    Solved Blacklist issue with SIP Trunk

I assume that 3CX sends back a 'reject' or 'don't want this call' signal to the SIP Trunk that presented the original call, my SIP Trunk has a 'emergency' number configured at the carrier...

    I am running 3CX 15.5, periodically my bandwidth.com trunk fails authentication too many times and ends up on the IP blacklist as blocked, causing my phone lines to be down.
