Hey Henning,

Thanks! Well, the problem is I can’t evaluate the header on the failure_route. That’s why I was trying with T_rpl, but hdr returns 0 (as int) of the header is not present, as opposed to $null…

Hello,

maybe just guard the assignment with the is_reply() function?

Or evaluate the specific header before actually assigning it with an if check?

Cheers,

Henning

Hello guys,

so i'm doing on a failure_route:

$var(xgws_in_reply) = $T_rpl($hdr(X-GWs));

which when it’s present on the reply is cool…

but when there is NO REPLY, then kamailio sets it to “0”… anyway over this?

i only want to know whether it is present on the reply

Regards,
