[OpenSIPS-Users] Dialogs not getting removed upon receiving BYE

Hi,
I'm new to opensips, and I'm having trouble with dialogs created from the
load_balancing module not being removed upon receiving the BYE when the
call is terminated.
I'm using opensips version 1.7.2 and have followed this example as well (
http://www.opensips.org/Resources/DocsTutLoadbalancing
).
Currently I'm testing it on two sip phones which are registered on the
opensips SIP Router (at times I'm using one sip phone as both the caller
and callee, rewriting the destination uri (automatically done through the
load_balance() method) as my IP to route the call back to the same sip
phone). Either way the dialog is not destroyed on bye and Wireshark output
shows that I'm receiving the 200 OK to both sides and the call gets cut
without any problem.
So, am I missing something on the config file ? Here's my config file....
*opensips.cfg*

I could give you the opensips debug output as well but due to the message
being too large I have excluded it... if need it please let me know and I
will reply with it :)
