Hi List,
I use Kamailio 5.2.x and I want to fetch an value from an X Header and do
some checks like "is not empty" and "should be an integer".
AFAIK per default all values are strings with the hdr function.
What are the best way for some validations within Kamailio script language?
if(is_present_hf("X-someheader")) {
$avp(routing_target) = $(hdr(X-someheader){s.int});
if(!ds_list_exists("$avp(routing_target)"))
Cheers

Hey Karsten,
I had a similar doubt and following Daniel's recommendation I went with the
same route you did (using {s.int} to convert to integer).
Quote from another thread: *"you can also convert the header value to
integer using the transformation {s.int <http://s.int/>}, that's safer if
you need to do other types of comparison such as > or <, because comparing
string values might give the result you don't expect"*
Hope this helps!
Joel.

Hi Joel,
Thanks for your quick response. Okay then I went this way and convert it to
int and do then the checking. The mailing list is a good source for best
practices questions.
I had some concerns about the core error warnings if the value is
alphanumeric or something else not numeric.
