Hi all, maybe someone on the dev list can jump in here too I have run into the wellknown problem with IAX about passing variables between servers. In my current 1.0.x network with IAX peers and Queues -- passing some extra variable information between Queue member channels is obviously not going to work. Googling shows some old discussions of an IAXVAR patch ......but I can't seem to find it anywhere. Anyone know about this or if the solution worked? Discussions seem to indicate that it worked .....as a sort of temp fix for those that needed it.... :-S Any help/suggestions appreciated -- -- Chris Earle System Solutions Specialist, Network Technologies Division CBL Data Recovery Markham Facility http://www.cbltech.ca Be committed to the environment. Please think twice before printing this email.

goto bugs.digium.com, Click View results, and enter IAXVAR.
I got 4 hits, one of which is the patch in question:

IAXVAR patch?

Quote:

Isn't this channel specific? Why is this being added? It does

not work with SIP. It does not appear to be architecturally generic.

Quote:

This gets added, but yet a channel specific enhancement for SIP

that would be beneficial for endusers does not get added. Again,
Asterisk is good at transferring > calls around, but when it comes
to end users, the developers just keep closing the tickets on the much
needed features.
Being able to pass variables around between systems is by *definition*
channel-specific, since the channel driver is the module responsible for
speaking a given protocol. Besdies, SIP already has (and has had for a
long time) a method for doing this (SIP headers). So does ISDN, for
that matter (IEs).

Also, insofar as changing things in the core for this, it isn't
necessary. Asterisk has had channel variables for at least as long as
I've been working with it. This is really just an extension of that so
that there is a way to send this kind of information to remote systems.

Finally, chiming in on this issue in the way you did is fairly childish.
It's not really related, even, just a whine about a feature which you
(incorrectly) equate with one that got shot down.

If you'd like to discuss a particular feature that was rejected, I invite you
to create a new thread to discuss it. Hijacking an existing thread is the
wrong approach.

I agree. However, I can't see ANY reason to not make the interface
similar to the interface used for SIP Headers, i.e. SIPAddHeader.

Stuff should work the same (from the perspective of the dialplan) across
channel types as much as possible.

The interface is actually fairly similar, although the name is not identical
for obvious reasons, of course (it's not SIP).

I would be very much interested in a common syntax. Unfortunately, it's not
quite possible in this case, because you can add multiple SIP headers with the
same name (and that's considered a feature!), but the namespace is flat for
IAX2 (i.e. if you set foo multiple times, only the last value endures). The
interface is very similar to channel variables, CALLERID() variables, and the
like, though.
