    Hi guys,

    in my activity log i get many lines like te folowing: (3cx v15)

    03/06/2017 10:03:35 AM - PBX has dropped a message with 'User-Agent: voip.ms' from IP xxx.xxx.xxx.xxx because it is on blocked UAs list

    xxx.xxx.xxx.xxx = ip of my trunk provider from voip.ms

    the ip adress in question is WHITELISTED in 3cx....

    should i worry about this ? ... i'm investigation a radom drop for incoming calls.....

    Hello @cmdias

    Please note that the word voip is commonly used in known hacking tools and 3CX ignores invites that contains the word voip in the user agent field.
    Please note that in SP5 released friday this has been fixed so make sure you upgrade to SP5 and provide us with a feedback
