[OpenSIPS-Users] $avp in codec_exists

[Jozsef CZOMPO]

Hi

I need to specify in database table the codec order per sip clients.  
So i'm created a table with some fields. But if use  
codec_exists('PCMU') it return true, when i'm using  
codec_exists($avp(s:codec)) i'm getting syntax error, and if i'm using  
codec_exists('$avp(s:codec)') i'm getting false. When i'm use xlog  
( "L_ERR", "$avp(s:codec)"); the result is PCMU, so the avp_db_query  
is working fine.

So, how can i use this?

Thank
