<DIV><FONT face=Arial size=2>Hi!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I noticed a "phenomenon" that I don't
understand:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I make accounting with ser. If all works fine, ser
puts into the database:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>sip_method: ACK</FONT></DIV>
<DIV><FONT face=Arial
size=2>i_uri:
sip:0182011542614xxxxxx@xxx.xxx.xxx.xxx:5060 (xxx.xxx.xxx.xxx = IP
of PSTN-Gateway)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>... and after the call, the BYE message reaches my
server.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>But sometimes, the ACK is logged in the database
like this (in the most cases form users "far away"):</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>sip_method: ACK</FONT></DIV>
<DIV><FONT face=Arial size=2>i_uri:
sip:0182011542614xxxxxx@<STRONG>my-ip</STRONG>:5060</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In this case, the BYE message doesn't reach my
server.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Does anybody know what could be the reason and why
ser logs the ACK from himself?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Many thanks!</FONT></DIV>
