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?


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?


Do you use a strong password for the admin AND user account?

Please follow next steps:
- Disconnect the phone from your network,
- Factory reset the phone to remove all (hack) settings
- Set a strong password for admin AND user account,
- Connect the phone to your network,
- Re-provisioning the phone.

Kind regards,
