Would the proposed B2BUA be based on dialog module?
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.
Would the proposed B2BUA also include SBC style features, such as limiting simultaneous calls, call times, etc?
Would it be possible to distribute the B2BUA to multiple parallel running servers?
