Hi, Jehanzaib!<br>
<br>
Bingo!  This is the cause of your strange double-pinging. You are using <br>
two NAT pinging modules at the same time: nathelper + nat_traversal.  <br>
And, of course, nat_traversal will keep on pinging the old value until <br>
its "virtual expiration" timer kicks in, ignoring the fact that the <br>
contact actually got refreshed within the user location by a new <br>
binding, xx.xxx.xx.xx:25004.<br>
<br>
Possible solutions:<br>
<br>
* stop using nat_traversal<br>
* stop using nathelper<br>
* keep using them both, but be careful not to arm them simultaneously <br>
(can be tricky)<br>
<br>
