In Asterisk 1.8, I used the following line in extensions.conf to allow me to pass “*82” in front of a dialed number, to disable the callerid block that’s normally on that POTS line:

; disable callerid block
exten => _*82.,1,Dial(${POTS}/${EXTEN})

But this seems to have stopped working when I upgraded to Asterisk
11.7. I get the following debug output, with a “no call pickup possible” message as soon as I press the ‘8’:

and then a busy signal.

I didn’t pay much attention to the differences between Asterisk 1.8
and 11.7 since everything seemed to still work … Can someone point me in the right direction?
