Sign in Common Area Phone on Remote Site

Hi,

I have provisioned a Common Area Polycom CX3000 within Lync 2010, but need to sign it in on a remote site.

DHCP is not setup on the remote site with the options and cannot be setup either.

If I tether the phone to a Lync client that is signed in on a PC on the remote site first, and then sign out, untether it and try and sign the phone in using the Common Area objects phone number and PIN, will this work?

Thanks

Paul
