moderate news: there is the expr app that is not exactly intuitive but can generate a random number as a function variable ${expr(randomize(&x);ceil(random(0,10,&x)))} This will eval to a random number from 1 to 10 (always start one number less than where you want to start) see: http://wiki.freeswitch.org/files/expr.html On Thu, Apr 8, 2010 at 6:29 PM, Michael Collins <msc@freeswitch.org> wrote:
Good news, bad news:
The good news is that the XML dialplan is a very efficient way of handling call routing. The bad news is that the XML dialplan is not a programming language. There is no "rand" function, so you'll need to do something different. One option is to use mod_distributor, however it is not "random" so that may not work for you. The other option is to call Lua or system or something and snag a random number.

Hi,
i'm slowly, but constantly moving from asterisk to fs.
Stuck on translating this into a freeswitch:
exten => s,1,Random(90:s,3) exten => s,2,Noop(his is hit 10% times) exten => s,3,Dial(SIP/8000)
What i need to do is put a bucket on some calling_number + destination numer with some random percent to a voiceguide and hangup.
i've found that memcache is very convinent way to put data into dialplan logic in runtime, so i plan to do:
<extension name="bucket_part_01" continue="true"> <condition field="${do_bucket}" expression=".+" break="on-true"/> <condition field="caller_id_number" expression="^123456789$"> <action data="do_bucket=${memcache(get b_${caller_id_number})}" application="set"/> <action data="bucket_part_02" application="transfer"/> <action application="hangup"/> </condition> </extension>
So above i check for caller_id_number in the memchache b_123456789 with option 1 Then i transfer to anoter extension:
<extension name="bucket_part_02"> <condition field="destination_number" expression="bucket_part_02"/> <condition field="${czy_robic}" expression="^1$"> <action data="bypass_media=true" application="set"/> <action data="hits=${memcache(increment hit_bucket_test)}" application="set"/>
AND HERE I do need some logic that does if Random() > 50%
<action application="answer"/> <action data="/usr/local/freeswitch/sounds/pc/weRbusyRightNow.wav" application="playback"/> <action application="hangup"/> </condition> </extension>
any cleaner approach or someone has done it better? note: don't want to use any lua, api or sth, just plain xml dialplan logic.
