OK, Giovanni, would you take the role of 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.

Hi Giovanni, Johan, Antonios,
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 ?

+1 it is an endpoint thing, trunk providers are wrong to ask
for it (what do they get from it?)
when you (trunk provider) know that the phone is actually
ringing, what do you gain? It has meaning when you control
the whole chain, end-to-end (carriers, IMS) not at all for
deskphone->itsp->trunk->whatever->carrier->endphone
But I know they (trunk providers) start to *REQUIRE* PRACK
So, probably a module, or an extension of an existing module,
can be warranted and welcome
Possibly on 3.6.X (that's the last LTS of the 3.0.0 series)
Let's open a thread on what functionalities can be useful in it?

Hi!
I also want to point out that its not done with PRACK
handling alone. Followup (multiple) UPDATE with codec
changes must be handled, too. Sometimes that lead
into AMR(WB)/PCMA/G722/OPUS transcoding in early
state. Including all the DTMF PT issues.
It is definitely a endpoint / softswitch feature.
I know those ignorant IMS guys pushing out their
internal mess to plain RFC3261 interconnects and
forcing tasks previously done by an MSC to the rest
of the world.

Giovanni on a side note, what to do with update ? do
you handle it locally or do you forward it to your
endpoint ?
BR, Johan.
