Exclude 4 extensions from delay "exten => _s-.,n,Wait(4)"

My company uses CUCM in combination with Asterisk to provide internal VOIP and voicemail.
Voicemail extensions are created in asterisk.
There is some added code in extensions_additional.conf > macro-vm as follows:

exten => _s-.,1,Answer
exten => _s-.,n,Wait(4)
exten => _s-.,n,Macro(get-vmcontext,${ARG1})
exten => _s-.,n,VoiceMail(${ARG1}@${VMCONTEXT},${VM_OPTS}u${VMGAIN})
exten => _s-.,n,Goto(exit-${VMSTATUS},1)

I did not create this code, and my only knowledge of asterisk is what I’ve picked up by looking around the web interface, but when I started it was explained to me by my predecessor that this adds a 4 second delay at the front of the voicemail announcement. e.g. caller is transferred to extension XXX (our extensions go direct to voicemail). There is a 4 second silence, then the announcement starts “please leave your message…”

We run an IVR with 3 options as well - I’ve been asked to remove the 4 second delay from the 3 extensions used as IVR destinations but keep it on all other extensions.

Is this possible, and if so please may I have some assistance setting this up?

Many thanks in advance,

You appear to be referring to some GUI. Asterisk-GUI is unspported (end of life) and FreePBX has its own web site. As usual, GUIs make simple thing easy and slightly more complex things difficult to impossible.

We don’t know where the actual “extension number” is held by the scripts that come with the GUI, so it is not possible to give a definitive answer. The current extension number appears to be s-${ARG2) and it looks like ${ARG2} is ${DIALSTATUS} with some extra values, so not very useful, and it means you can’t use the neatest way of doing this with pattern matches on the extension number. You are therefore going to have to find a variable that contains the actual extension number and use GotoIf to bypass the wait on a match, or Execif to conditionally execute the Wait. My guess is that it is ${ARG1}.

Hi david55, thanks so much for your response. I’ve been told my base is freepbx. The GUI appears to be something called trixbox.

In any case, I am apparently modifying this file: /etc/asterisk/extensions_additional.conf

Thank you so much to Cyford33 on the #asterisk IRC channel. This code partially does what I need.

The four extensions I wanted to exclude from the 4 second wait were 408, 409, 410 and 416.

exten => _s-.,1,Answer
exten => _s-.,n,GotoIf($["EXTEN" = "407"]?vm:)
exten => _s-.,n,GotoIf($["EXTEN" = "408"]?vm:)
exten => _s-.,n,GotoIf($["EXTEN" = "409"]?vm:)
exten => _s-.,n,GotoIf($["EXTEN" = "410"]?vm:)
exten => _s-.,n,GotoIf($["EXTEN" = "416"]?vm:)
exten => _s-.,n,Wait(4)
exten => _s-.,n(vm),Macro(get-vmcontext,${ARG1})
exten => _s-.,n,VoiceMail(${ARG1}@${VMCONTEXT},${VM_OPTS}u${VMGAIN})
exten => _s-.,n,Goto(exit-${VMSTATUS},1)

If I dial 408, 409, 410 or 416 directly, they are excluded from the 4 sec delay as expected. However if I dial the IVR extension 407, then choose one of the options e.g. 2, I then hear a 4 sec delay, then the unavailable announcement from the respective extension.

Any idea why these extensions are not being excluded when going through the IVR?

Trixbox is abandonware. Its developer won’t support it and they have closed down the peer support forum for it.

The extension at that point is a string beginning in “s-” and ending in a status code, not the number that was dialled.
