Predial Hook destroys Wake-Up Calls

[AdFun7911]

I’m using the code listed in this topic:

Dynamically exclude own extension from queue or ring group

I want to suppress calls from all extensions to themselves so that your phone doesn’t ring when you’re calling a ring group or queue you’re in. @lgaetz already recommended using a dialplan hook. I used macro-dialout-one-predial-hook and macro-dial-ringall-predial-hook for that and this works in fact well, but not for ring groups. When calling a ring group you are in, the phone rings, but when answering on a different line, it hangs up (like it should before even ringing). That’s the code I used…

[macro-dialout-one-predial-hook]
exten => s,1,NoOp(Entering user defined context macro-dialout-one-predial-hook in extensions_custom.conf)
exten => s,n,ExecIf($["${CALLERID(num)}"="${CONNECTEDLINE(num)}"]?Hangup())
exten => s,n,MacroExit

But it seems to destroy the wake-up calls:

-- Executing [s@macro-dialout-one-predial-hook:1] NoOp("Local/331@originate-skipvm-00000039;2", "Entering user defined context macro-dialout-one-predial-hook in extensions_custom.conf") in new stack
-- Executing [s@macro-dialout-one-predial-hook:2] ExecIf("Local/331@originate-skipvm-00000039;2", "1?Hangup()") in new stack

I don’t understand why it’s executing this line. The caller id is entirely different and set to the default *68.

Do a DumpChan() to find out what unique data wake up calls has and send to MacroExit.

Something like this:

[macro-dialout-one-predial-hook]
exten => s,1,NoOp(Entering user defined context macro-dialout-one-predial-hook in extensions_custom.conf)
exten => s,n,Gotoif($["${whatever_wake-up}"="something"]?done)
exten => s,n,ExecIf($["${CALLERID(num)}"="${CONNECTEDLINE(num)}"]?Hangup())
exten => s,(done)n,MacroExit

Thank you, that was a great idea. The problem is obvious:

CallerIDNum=        *68
CallerIDName=       Wake Up Calls
ConnectedLineIDNum= *68
ConnectedLineIDName=Wake Up Calls

It seems I have to check if it’s a wake up call, too. Does anyone have an explanation for why both are the same?
