Hi, Jehanzaib!

Bingo!  This is the cause of your strange double-pinging. You are using 
two NAT pinging modules at the same time: nathelper + nat_traversal.  
And, of course, nat_traversal will keep on pinging the old value until 
its "virtual expiration" timer kicks in, ignoring the fact that the 
contact actually got refreshed within the user location by a new 
binding, xx.xxx.xx.xx:25004.

Possible solutions:

* stop using nat_traversal
* stop using nathelper
* keep using them both, but be careful not to arm them simultaneously 
(can be tricky)

Regards,
