[OpenSIPS-Users] syntax error in cfg file

[Vlad Paiu]

Hello,

It seems the OpenSIPS parser does not tolerate well constructs like
     if ( ($var(t2) - $avp(diff) ) <= 0 )

with expressions in the if conditions.

While we fix this, a quick work-around would be to use an auxiliary 
variable, like :
     $var(my_aux) = $var(t2) - $avp(diff);
     if ($var(my_aux) <= 0)
         ....

Also, I see that in your script you are using division operations. I 
hope that you are aware that OpenSIPS has only integer support, so you 
result vars will be truncated to int.
If you want to use float operations, see 
http://www.opensips.org/html/docs/modules/devel/mathops , but please 
note that it is only available in the current OpenSIPS trunk.

Best Regards,
Vlad
