Hi,

The issue is that $avp(id_asterisk) contains an integer, so you cannot 
do "integer + string" concatenation in OpenSIPS.  However, what's 
interesting is that the OpenSIPS config language actually allows "string 
+ integer" concatenation!  So just fix it like this:

$var(result) = "" + $avp(id_asterisk) + "|" + $avp(codecs);

Best Regards,
