<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I'm using qualify= on my asterisk server that provides outgoing
pstn calls to a few companies.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I've got one client in particular that has their own
asterisk server which is connected to my server.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This client seems to be having a nat issue. It's not a
connectivity issue as i've tried constant pings and the line is up constantly.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I'm getting the following:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>

<p class=MsoNormal>Looking at the sip log, on the client's server, the sip OPTIONS
packets arent being received. Then suddenly the sip packets start being
received again. (without sending out a new packet to open up the nat mapping). I've
tried replacing the router because I thought it was faulty.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Here is the SIP log from my server: http://pastebin.com/ZbDYGG9R<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Finally, I tried mapping port 5060 so to avoid NAT issues,
but that didnt help. Could there be an ISP problem?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any assistance would be appreciated.<o:p></o:p></p>
<p class=MsoNormal>Many thanks<o:p></o:p></p>
