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.

Could you come up with a test case please?  I am completely unable to
replicate those results:

    -- Executing [8165 at digium:1] Set("SIP/103-00000000",
"IAXVAR(foo)=bar") in new stack
    -- Executing [8165 at digium:2] Set("SIP/103-00000000",
"IAXVAR(bar)=foo") in new stack
    -- Executing [8165 at digium:3] Dial("SIP/103-00000000",
"Local/8166 at digium") in new stack
    -- Executing [8166 at digium:1] NoOp("Local/8166 at digium-c86d;2",
"foo=bar, bar=foo") in new stack
    -- Called 8166 at digium
    -- Auto fallthrough, channel 'Local/8166 at digium-c86d;2' status is
'UNKNOWN'
