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.

I am not an employee of Yealink.
Dutch is my native language, not English. Apologies for my imperfect grammar.
Please do not send unsolicited PM messages. I will not answer them.
