[asterisk-users] beta9: how to set callerid on incoming iax?

[sean darcy]

iax.conf:

[nhi]     ; receives calls
type=friend
secret=password
context=longdistance
qualify=yes
trunk=yes
callerid="test" <447>


extensions.conf:

[longdistance]

exten =>_1NXXNXXXXXX,1,Answer()
exten =>_1NXXNXXXXXX,n,NoOp(${CALLERID(num)} first stanza)
exten =>_1NXXNXXXXXX,n,Dial(Zap/g0/${EXTEN})
exten =>_1NXXNXXXXXX,n,Congestion()
exten =>_1NXXNXXXXXX,n,Busy()
exten =>_1NXXNXXXXXX,n,Hangup()

from cli:

Executing [xxx at longdistance:1] Answer("IAX2/nhi-2", "") in new stack
Executing [xxx at longdistance:2] NoOp("IAX2/nhi-2", " first stanza") in 
new stack
Executing [xxx at longdistance:4] Dial("IAX2/nhi-2", "Zap/g0/xxx") in new stack

So extensions.conf see the _channel_ as the callerid(num). Is this a 
bug, or am I messing something up?
