is my test cloud pbx server hacked? *NEW FusionPBX user*

I'm trying to auto-provisioning a grandstream phone, extension 3001 is mine

extension 4559 and 100 and 4560 they are not mine. Does this mean my system is compromised? any immediate security tips

Thanks!
 
By changing your SIP port on Internal Profile you'll block 100% of these automated attempt at your server. It won't block a targeted attack tho.
I've tried but somehow it doesn't work, even if I change the port on voip innovation and fusionpbx, all communications still use 5060.
but my next step after figure out how the auto-provisioning works will be to external profile or change the port on the internal profile.

Thanks for the advice
