Hi<br>
<br>
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?<br>
<br>
<br>
<b>add file conf/directory/default/pstn.xml containing</b> <br>
<pre><include>
<!-- Add ip= to constrain to specific IP address for a little extra security -->
<user id="Anonymous"/>
</include>
</pre>
<b>change following in conf/sip_profiles/internal.xml</b>
<pre><param name="accept-blind-reg" value="true"/>
<param name="accept-blind-auth" value="true"/>
Thanks advance
O
