[Shane Young]

Yup, I noticed this last December when I upgraded to 1.4.

>
> 1. Create a file in /etc/asterisk called setversion.sh which
>    contains two lines:
> 	#/bin/sh
> 	echo ASTERISK_VERSION=$(/usr/sbin/asterisk -V)
> 2. Make it executable: chmod +x /etc/asterisk/setversion.sh
> 3. Add the following to /etc/asterisk/asterisk.conf
> 	[options]
> 	execincludes => yes
> 4. Add the following line to extensions.conf up in the [globals]
>    section
> 	#exec </etc/asterisk/setversion.sh>
>
> The other thing you need is [macro-fastbusy], but I'll discuss that in
> a completely separate thread (subject: Congestion and Busy Handling).
> You could, of course, do what you normally do when the Dial command
> fails.
