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...
Thanks in advance! Uriel

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
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

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 Alex, :)
I was just trying to keep it simple, but let me explain a little bit.
I'm using a Proxy+RTPProxy in mhomed mode. I have a public and a private IP on that Proxy and route calls in and out of a network.
As I have many carriers that want different ANI and DNIS patterns I have to deal with some flexible configuration. So I created a table where I hold a special regex rule for each of them and then I get the regex in realtime (with SQLOps) into an AVP ($avp(s:carrierAniRegex)). Then I get the ANI for the incoming leg and store it on an AVP ($avp(s:ANI)).
When I execute this regex I get the new ANI to replace in FROM, RPID and PAI.
To be honest it's actually more complex because in a per carrier basis, I configure if I'll use a fix ANI, a REGEX edited one or I'll leave it transparently. :)
If someone would like to do something similar, I'll be glad to share scripts and configs.
Best regards, Uriel

Maybe the database can apply the regex and give you the transformed result? Databases are quite capable these days. I do this in PostgreSQL all the time.

Hi Alex,
Nice approach. I'll try that too but I'm affraid about DB performace issues (I have a very busy mysql).
Thanks a lot. Uriel
