Would the proposed B2BUA be based on dialog module?
I am not sure the 'dialog' module would be of much help here, prima
facie, but it's certainly possible that some aspect of its dialog state
machine could be borrowed for a UA dialog layer. It would stand to
reason that if TM can provide the UAC transaction layer, as it already
does in limited cases for the 'uac' module, then 'dialog' can provide
the dialog layer.
If so, I remember a few years ago that there were some
fundamental
problems with dialog module and it was proposed to design a new
dialog-ng module. I haven't followed what (if anything) happened.
The module exists in parallel, but seems to be used only by the IMS
folks, and designed in a manner complementary to IMS:

Would the proposed B2BUA also include SBC style
features, such as
limiting simultaneous calls, call times, etc?
My proposal would be to limit the ambitions of such a module as much as
possible, in order to make its implementation more likely. :-)
