on firewall</DIV>
<DIV><BR></DIV>
<DIV><SPAN class=291200714-07072004><FONT face=Arial size=2>I'm using Asterisk
to registry several DDI's to a sip proxy (pipecall.com). Everything works fine
apart from several times a day my firewall (zywall70) reports a UDP port scan
attack from the pipecall sip proxy. I can't seem to work out why this should
be. All I could think was that the sip registry was expiring and causing some
strange probing from the proxy, is it possible to alter the expiry on a sip
channel or does anybody have any other ideas?</FONT></SPAN></DIV>
