The dial plan is parsed and extensions created, and then they are run.  The ${callsubject} in your log line is evaluated in routing state, before httapi is run in execute state

I got this working (with the help of this list) some time ago, but for some reason it seems to have stopped working.

I’m setting a variable ‘callsubject’ in the dialplan via httapi, for which I added a column in the channels table:

ALTER TABLE channels ADD COLUMN callsubject VARCHAR(256)


 

      <action application="httapi" data="{url=https://server/${destination_number}}”/> <!-- gets variable callsubject as ’test’, amongst other stuff -->
      <action application="log" data="CRIT callsubject: ${callsubject}”/> <!-- correctly shows ’test’ -->


And yet, whilst the column shows up in ’show channels’, the leg in question has an empty value.

What am I missing, maybe?
