...guration is handled by FreePBX 2.11. I want to understand the dialplan behavior in order to figure out why the CDR(recordingfile) is blank on the CDR records despite the dialplan setting it. My program generates the calls by setting Channel=Local/NUMBERTODIAL at from-internal and by setting Exten=QUEUENUM, Context=from-internal, Priority=1 . The FreePBX-generated dialplan results in the following trace as seen in the Asterisk console.
