Dynamic Hints Ast 13 :database

Asterisk Asterisk General

Hi I am having trouble getting this to work.
I am using realtime sip and would like to get my hints working dymaically as well.

I came across a few threads that this should be possible and it should work.
The threads that I came across are:
lists.digium.com/pipermail/aster … 57678.html

here the code

[internal]
include =>branches
exten => _2XX,hint,${DEVICE_GETHINT_DEVICE(${EXTEN})}
exten => _2XX,1,Verbose(3,*** INTERNAL Content ***)
same => n,NoOp(HINT GETHINT = ${DEVICE_GETHINT_DEVICE(${EXTEN})})

[code]cluster-spare*CLI> core show hints

-= Registered Asterisk Dial Plan Hints =-

_2XX@internal : ${DEVICE_GETHINT_DEV State:Unavailable Presence: Watchers 0
[/code]

When I statically type hints in and match it it works
what am I doing wrong

thanks
Zak
