[SR-Users] Dialogs not deleted on BYE

[Daniel-Constantin Mierla]

Hello,

dialog_ng is more or less tailored for IMS modules, dialog module is
still in use and very actual.

If you are not using IMS module, you should try the dialog module. I
haven't seen any issues for it lately and if there are, they will get fixed.

Cheers,
Daniel
