[Standards-JIG] Defining IAX transport over jingle

I see in my scenario an asterisk gateway mostly just being an
information hub. Replying to DISCO/Jingle queries but then the IAX
client just simply calls the extension.

When I wish to call you how do I distinguish which 2 of the IAX methods
you support?

I believe in the Jingle Signaling JEP has a feature section is that
correct? Maybe we need 2 features for IAX/SIP being IP to IP or through
a PBX.

I think I'm a bit in the same boat as you. I know what I need out of
this but confused which solution is best and most clean.

The way I see it is, there might be multiple gateways on 1 server for
Asterisk. One might be a chan_jingleaudio which connects Jingle Audio
capable clients Asterisk. Another would be an Asterisk gateway that
doesn't do Jingle Audio but supports DISCO queries for asking how do I
contact Antonio.

Like I said I know what I need but ensure at which route to take.

You could DISCO the asterisk.server.com for Antonio's extension #, or do
you query for his VCard to find it? Etc etc.. Many JEP's I think could
be used but which is best?

hmmmmm three points goes to Simon :)

I'm not sure about this, maybe this has to be implemented by a
chan_jingle_iax into the Asterisk. Maybe Asterisk (PBX) box could have
his roster mapped with extensions, and connected to the Jabber server
like a bot  :-/

Ohhhh I can see the scenario, sorry is really late and a long day. I
promise to think slowly tomorrow morning with a cleaner mind ;)

Yes you're right, maybe all this stuff is related to the entities
implementation and not to the specification :-/

Thinking a little (only a little), not seems to be necesary to include
the extension we want to call into the transport because this goes into
the dial string of the IAX library.

Take care,
