<DIV><FONT face=Arial size=2>Do some reading about contexts in *. Basically, you
want all "public" sip requests to land in a dialplan context that has no access
to PSTN, and requests from your own SER box(es) to land in another context (that
DOES have access to PSTN).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>You can achieve this by adding an entry to your
sip.conf for your SER box with it's IP address (and context)
specified.</FONT></DIV>
