Good Morning!
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.

Kind regards,
Frank.

Hi,

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,
Frank.
