There may be an easier and more elegant and more performant way to accomplish what you are trying to accomplish, but we cannot know without seeing the pattern and the regex. :)

Hi Daniel,
Actually I'm going to partially take your advice, implementing the following:
exec_avp("echo '$avp(s:ANI)' | sed '$avp(s:carrierAniRegex)'", "$avp(s:ANIegress)");
I'll check for performance issues later but surely this simplifies a lot the config.
Thanks! Uriel

Hey guys,
I'm using Kamailio 1.5.3-notls and need to apply some re operation to an AVP.
The problem I have is that my re expression is held in an AVP, so the parser is not recognizing it :(
Would it be very hard to change that behavior? Any ideas/tips to implement?
This code route[16] { ... avp_subst("$avp(s:ANI)/$avp(s:ANIegress)", "$avp (s:carrierAniRegex)"); ... }
returns this error ERROR:avpops:fixup_subst: avpops: bad subst re $avp (s:carrierAniRegex)
This code route[16] { ... avp_subst("$avp(s:ANI)/$avp(s:ANIegress)", $avp (s:carrierAniRegex)); ... }
returns this error CRITICAL:core:yyerror: parse error in config file, line 751, column 51-74: syntax error CRITICAL:core:yyerror: parse error in config file, line 751, column 74-75: bad arguments
Do you think some other way I can achieve this? Be aware I'm using SQLops to get realtime the value of the expression...
avp_subst() cannot help here, there is no support for taking the substitution expression from a variable.
What you can do in 1.5 is either look at dialplan to see if it fits your needs (it can do such substitution with expressions taken from db at startup, which can be reloaded at runtime), otherwise try using perl module (or exec in 1.5+ and lua/python in devel).
Cheers, Daniel
