Asterisk channel variable set before dialplan executes?

  • 772

The backstory is that I am trying to debug an issue I am having with FreePBX currently. The channel variable REC_STATUS is set to RECORDING when it shouldn't be.

After quite a bit of troubleshooting and no sign of anything in the dialplan that could be causing this, I decided to insert a NoOp(${REC_STATUS}) as the first line of dialplan code to be executed for a new incoming call. Guess what? REC_STATUS is already set to RECORDING as of the first line of dialplan execution for these new calls.

My question is this: how is this channel variable already set before the dialplan starts executing?

  1. It turns out that there's a way to set global variables in Asterisk, and when you go to request a variable for a channel, the global value will be shown if the variable has not been set otherwise on the channel.

    I resolved my issue by executing the following on the dialplan once:

    Set(GLOBAL(REC_STATUS)=)

    Using any of these options did not work:

    Set(REC_STATUS=)
Set(_REC_STATUS=)
Set(__REC_STATUS=)
