Juniper router

[LukeL]

Is anyone else using Juniper routers with 3cx? I would like some tips and directions to optimize our qos and keep hackers at bay. I already moved SIP port 5060 to another port number and it reduced by a lot the number of hacker warnings. Thank you for your help.

Do you have remote phones and/or remote 3cx phone clients? If all you have is a voip provider than restricting traffic to only your VOIP provider IP address space would stop all of the hack attempts.
