Summary:                    Possible problem with IAXVAR
Description: 
A call comes in one a server. IAXVAR(call_id) is set on the IAX-channel.
Then a dial(Local/..) is done.

When trying to read out IAXVAR(call_id) on the local channel I only get
this:
<Local/115 at transcontext_220-4c7b;2>AGI Rx << GET VARIABLE IAXVAR(call_id)
<Local/115 at transcontext_220-4c7b;2>AGI Tx >> 200 result=1
(ÿÿÿÿ0010|343.6)

It was initially set this way (on the same server):
<IAX2/pbx7-5666>AGI Rx << SET VARIABLE "IAXVAR(call_id)"
"pbx3_1263978343.6"
<IAX2/pbx7-5666>AGI Tx >> 200 result=1

The value I get when I read the variable seems to be a mix of the last 5
on the iaxvar ("343.6") and the last 4 of the previously read variable
(0010): 
<Local/115 at transcontext_220-4c7b;2>AGI Rx << GET VARIABLE origcallerid
<Local/115 at transcontext_220-4c7b;2>AGI Tx >> 200 result=1 (38600010)

I don't know if this should be possible, but it would be nice if it was.
Anyway, the IAXVAR function should return empty or so if not.

I've tried a lot now, but I can't reproduce the issue with crazy y's with
other code than some internal that I can't publish. Sorry for this.


However, this config will show that the IAX-variables is not kept through
an assisted transfer (I wrote blind transfer earlier, but that was wrong).
It's a stripped down version of my other code, not requiring any databases
and several AGI scripts.

[iaxvar_test]

exten => s,1,answer
exten => s,n,set(TRANSFER_CONTEXT=iaxvar_transfer)
exten => s,n,set(IAXVAR(test)=test123)
exten => s,n,dial(Local/my_number at outgoing/n,,t)

[iaxvar_transfer]

exten => 111,1,noop(${IAXVAR(test)})
exten => 111,n,wait(10)

I you call in to iaxvar_test and then do a blind transfer to '111' the
variable will containt the correct information.
But if you do an assisted transfer the variable will be blank.

All IAX and local channels should inherit the IAXVAR's ?
