Thanks a lot.

but I can not see how the non-secure profile is connected to the phone?

when configuring phone there are only standart sip profile.

I mean I want to change configuration of only one phone. not all of them.

You ALWAYS have to configure the SIP profile and phone security profile for devices, they are MANDATORY fields. And those are two different settings in the device page.

Assign the phone security profile with UDP only to the phone you want.
