mask the calling number from going throught PSTN

[cchajii]

hello

i'm using ip phones with gateway (3640) to pstn, my Pb is that the calls from ip phones to pstn have a calling number = dn of the ip phones. i want to mask the calling number ( private ) so no calling number will go throught pstn.

thanks for help
