starting a new thread (was your idea :D) here and filling in all
the PRACK related requirements that you have in mind at this step
- and we can use that as starting point for the discussion.<br>

<p class="MsoNormal"><span style="font-family:"Courier New"">Hi Giovanni,
Johan, Antonios,<br>
<br>
Talking about the PRACK, yes, it sounds like a good idea to
get such support in the dialog module. And yes, we need to
start with drafting the functionality to be provided -
should we do this over the #2076 github ticket (mentioned by
Giovanni) or open new thread here, backed-up by a GH wiki
page to aggregate the requirements ?<br>
<br>
Best regards,</span><br>
