<tt>Hi Dinusha,<br>
<br>
Most probably OpenSIPS does not "see" the BYE - this may happen
because:<br>
- BYE is not reaching opensips<br>
- BYE does not have in RR header the "did" cookie <br>
<br>
Try to run opensips in full debug (set debug=6) and post the log
related to the BYE processing, to see what is going on there.<br>
<br>
Regards,</tt><br>

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.
<br>
I'm using opensips version 1.7.2 and have followed this example as
well (<a moz-do-not-send="true"
href="http://www.opensips.org/Resources/DocsTutLoadbalancing"
target="_top" rel="nofollow">http://www.opensips.org/Resources/DocsTutLoadbalancing</a><br>
).
<br>
<br>
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.
<br>
<br>
So, am I missing something on the config file ? Here's my config
file....<br>
