Hello,

Parameters to SIP headers are ';' separated.  ',' is used to concatenate multiple headers onto a single line.  The {param...} transformation is intended to process SIP header parameters.

However, there is a new feature in Kamailio 4.1 (currently in a pre-release/testing phase) that allows you to specify the delimiter value.  That may do what you require.

Please see: http://www.kamailio.org/wiki/cookbooks/devel/transformations#paramvalue_name_delimiter

Regards,

Peter

Hi,

Transformation {param.value, param_name} returns incomplete or empty values when parameter value contains comma (,).

See next example:

$avp(my_var)="a=val_a1,val_a2,val_a3;b=val_b";

in next transformations:

$(avp(my_var){param.value, a}) returns 'val_a1'

$(avp(my_var){param.value, b}) returns empty string

Seams that comma in parameter value conflicts with semi column separator.

Is this bug or wrong documented?
