Polycom Basefile Edit Phantom Calls

I know there is a line that you can add to the polycom config file that will tell it to only allow traffic from certian IP address. I’m assuming that this will stop the phantom calling on the vvx400’s

I belive the line is something like this

of course i change the ip for security reasons.

My question is where would i put this Basefile Edit. I know it’s under the brand which is polycom, however i am lost on where to put this information so it will push it to all my phones telling them only allow traffic from my server

Sorry It Cut out my snip

<voIpProt> <voIpProt.server voIpProt.server.1.address="192.151.XX.XX" voIpProt.server.1.port="0" /> <voIpProt.SIP voIpProt.SIP.enable="1"> <voIpProt.SIP.outboundProxy voIpProt.SIP.outboundProxy.address="192.151.XX.XX" /> <voIpProt.SIP.requestValidation voIpProt.SIP.requestValidation.1.method="source" voIpProt.SIP.requestValidation.1.request="INVITE" /> <voIpProt.SIP.alertInfo voIpProt.SIP.alertInfo.1.class="ringAutoAnswer" voIpProt.SIP.alertInfo.1.value="Auto Answer"/> </voIpProt.SIP> </voIpProt>

anyone know what i’talking about
