Feedback? As in high-pitched squealing?

I can't imagine any circumstance under which a SIP phone would even
allow feedback.

Maybe you mean echo?

You might also be talking about sidetone, which is the portion of your
own voice that the phone pipes back to you so that you can adjust your
voice accordingly.

Sidetone can be set in the phone configuration; before you do that,
though, I need to know what you mean by feedback.
