<DIV><FONT face=Arial size=2>Hi i'm trying to connect to the PSTN in the
following way</FONT></DIV>
<DIV><FONT face=Arial size=2>sip ATA -> * -> gnugk -> Cisco AS5300
-> PSTN</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm using asterisk CVS-HEAD-06/01/05-14:33:15
running over RH EL3 </FONT></DIV>
<DIV><FONT face=Arial size=2>Asterisk-Oh323 0.7.2 pre1</FONT></DIV>
<DIV><FONT face=Arial size=2>Open H323 v1.13.5</FONT></DIV>
<DIV><FONT face=Arial size=2>pwlib v1.6.6</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>and I'm having a lot of trouble, gnugk and * both
have public ips and are not behind any type of firewall, the sip ATA is behind a
firewall and has a private ip but there's a stun server working and the
connection works fine.</FONT></DIV>
