[OpenSIPS-Users] problem using scripting variables AND inject random delays

[amar mahmoud]

Hi all,
       i am quite new to use opensips, i have been using SER since last week.
 
i want to use opensips to inject a delay then relay SIP messages, actually there is function "sleep" under cfgutils.so module, i have tested it .. it is working fine, my problems are:
 
1/ i have problem using scripting variable i want to do like that:
 
  # define variable
$var(a) = 10;
 
 # then
 
sleep ("$var(a)");
 
but the config file does not accept that, it gives error  while when i use  sleep("10") there is no problem... so do i have a problem using that and if yes how can i solve this.
 
2/ i need to implement this delay to be a random variate where i can use different distribution like exponential or   normal, does any one try to do that before or have an idea how i can implement that
 
any ideas are appreciated.
 
 
Amar
