[SR-Users] Dialog - timeout for dlg with CallID

Correct me if I'm wrong, but not all within-dialogs are 'calls', for e.g.
NOTIFY with a preset Route after SUBSCRIBE, wondering how dlg_manage()
would treat those, would it count them as 'calls'?

Not to mention that docs mention "dlg_manage() - this makes sense only for
initial requests)
