Sure! This is one of my favorite features.
Let's say I have a definition for my phone in sip.conf, and it looks
something like this:
[myphone]
secret=verysecretpassword
type=friend ; a friend is both a user and a peer
host=dynamic ; phone will register to Asterisk
disallow=all
allow=gsm ; first, try to negotiate gsm
allow=ulaw ; the try ulaw
setvar=MYVAR=blah
Whenever a call comes into Asterisk from this particular phone, Asterisk
will automatically create a channel variable named MYVAR, and ${MYVAR}
will contain the value "blah". I can then use it for whatever purpose I
see fit within my dialplan.

Well, Jared, but that's the reverse. You stripped out this important
part:
" am trying to define it for a peer that's used when making calls
using the originate ami call, but it seems to not have any effect."
The important thing with your lesson was that SETVAR is only used on
INCOMING calls from
devices, not outbound calls TO devices. Using ORIGINATE to call a SIP
peer, there's no variables
set from sip.conf.

So, wouldn't it be great to enable setvar for outgoing calls too?

Absolutely true... and I'll make up for it by pointing out that if
you're using the Originate manager command, you can set channel
variables by adding the "Variable" setting to your manager command:
Action: Originate
Channel: SIP/myphone
Context: test
Exten: 123
Priority: 1
Async: True
ActionID: ThisIsMyVeryOriginalActionID
Variable: MYVAR=blah|ANOTHERVAR=baz

Well, maybe in the outbound channel then. But that won't help much.
mixing the caller's and callee's variables in the INCOMING channel
would be messy and only cause issues.
But there's another way. Hint hint. Friday afternoon hack.

Particularly, I want to set the SIPADDHEADER variable dynamicly for peers
with rt-engine. Working around it might be possible, but having the thing
working transparently for Dial and Originate would be great.

That should work today with the unofficial backdoor I implemented.
sipaddheader just adds a few channel variables that the outbound
channel inherits.
If you add them yourself with
setvar=_SIPADDHEADER99=X-peeraccountcode: 12345
I think that should work. Out of the box, like magic.
This of course only works with calls FROM peers.
Have a nice weekend!

Ok,
Now I have a friday afternoon patch for the community.
In the branch
http://svn.digium.com/view/asterisk/team/oej/peer-chanvars/
there's an addition to the SIPPEER() dialplan function where you can
retrieve a setvar= channel variable defined in sip.conf for the peer.
The branch is based on 1.4 and the patch will soon be included in the
1.6 trunk.
This way, you can for example add a variable called "CELLPHONE" with
the peer's cell phone number. If dial(sip/olle) fails, I can now do
dial(zap/${SIPPEER(olle,chanvar[CELLPHONE])})
This is something I came up with a few weeks ago when I created a PBX
based on Asterisk for a company, something that I don't do much, since
I normally use Asterisk in carrier environments with SIP proxys. Doing
this little PBX project was a lot of fun and I learned a lot.
Have a nice weekend!
