I am facing some problems with my IP Phone SIP-T22P, this is directly connected to the internet, and this is causing me to have been hacked and redirected my calls.
how do I block and allow only the ips listed to have access to the device?

Hi,

Setup a strong password, 24 char or more, should be sufficient.

Good Morning!
for invasion it worked perfectly.
and to avoid invite do you have any suggestions on where to block?
