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

Hi Dinusha,
Most probably OpenSIPS does not "see" the BYE - this may happen because:
- BYE is not reaching opensips
- BYE does not have in RR header the "did" cookie
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.
