The nonexistent context: http://www.freepbx.org/forum/freepbx/development/warning-messages-from-a-freepbx-2-7-0-4-log

The DB and DB_DELETE, I have no clue as I don’t know where they are coming from.

Look in the log file just before the warning and see why you get it. I suspect that the dial plan tries to delete a DB key and the key does not exists. Harmless warning.

Here are a few lines from above the warning messages

It’s a WARNING which Asterisk tends to be fairly verbose about. The logic is fine, if it’s not set then it’s not equal to the condition and the logic flows properly.

We could go through extra pains to check if variables are set before using them in cases like this but the only effect that has is adding inefficiency in the dialplan which is more detrimental then an extra warning in the log file…

It seems that row 3 of macro-vm in extension_additional.conf is bugged and gives the func_db.c: DB requires an argument, DB(/) error

exten => s,n,GotoIf($[“foo${DB(${BLKVM_OVERRIDE})}” != “fooTRUE”]?vmx,1)
