Hi

There is a wiki on the web which describes how to use a Grandstream FXO device with freesiwtch and recommends the following settings. How big a security hole is this creating and is there a better way to do this? Also, what would the syntax be for the "Add ip=" recommendation?

add file conf/directory/default/pstn.xml containing

<include>
  <!-- Add ip= to constrain to specific IP address for a little extra security -->
  <user id="Anonymous"/> 
</include>

change following in conf/sip_profiles/internal.xml

<param name="accept-blind-reg" value="true"/>
<param name="accept-blind-auth" value="true"/>


Thanks advance
O
