How to set call restriction on 3911 sip phone?

[Michael Ciulei]

Hi all,

I deployed a CME 4.2 and 35 sip phones to a customer. So I have to set some call restriction on some SIP extensions to call local phones only or a white list of external phones. Can anyoane tell me how can I do that?

Thanks in advance,
