[OpenSIPS-Users] Dialog does not end

[Bogdan-Andrei Iancu]

Hi Anton,

Try to use dlg_list MI command and see the ongoing calls. It looks like 
some calls, from opensips perspective, do not close - you need to run a 
sip tracing and correlated with the dialogs in memory, to learn why some 
do not close: missing BYE ? malformed BYE ? BYE with no did ?
