RE: Trust Control Causes Problems
Hi Dan,

I suppose you mean Trusted Certificates as you speak for Trust Ctrl?

Please try below settings to block random IP calls.
Go to “Features > General Information”
- Accept SIP Trust Server Only -> Enabled
- Allow IP Call -> Disabled

If you have many phones you can modify and use the provisioning template.
Please let me know.

Hope this helps.

Kind regards,
Frank.

I am not an employee of Yealink.

Please do not send unsolicited PM messages. I will not answer them.
