[OpenSIPS-Users] [OpenSIPS-Devel] Planning next release - Roadmap

[Ovidiu Sas]

There are no various confirmed dialogs.  Once a dialog is confirmed,
all the other branches are canceled.
In the current implementation, the dialog module does not care about
the number of early dialogs (it is transparent) because there's no
specific code to deal with early dialogs.
Having several PRACKs for different early dialogs going through the
same dialog should work just fine.

Ovidiu Sas
