Hello,

just adding that the tobody transformation could be handy to extract the user or uri part of a Diversion header, not to fight with subst expressions:

Cheers, Daniel

Hi,

I have not tested this, but try:

$avp(s:divhdr) = $(hdr(Diversion)[$var(i)]); avp_subst("$avp(s:divhdr)", "/.*sip:+45(.*)(@.*)/\1/"); # Extract number between +45 and @

if (is_user_in("$avp(s:divhdr)", "1") { ... }

Please note that there can be more than one Diverseion header. In that case you can use:

                    $var(i)=0;
                    while($(hdr(Diversion)[$var(i)]) != $null ) {
                            $avp(s:divhdr) = 

$(hdr(Diversion)[$var(i)]); xlog("L_WARN", "$avp(s:divhdr)");

                            $var(i) = $var(i) +1;
                    }

Dear List

I am currently using the group module to authenticate inbound
calls using the From header using the below code:

         if (!is_user_in("From", "1")) {
         sl_send_reply("403", "NOT ALLOWED");
         exit;
         };
         };

I want to now authenticate the Diversion header, when the call is
diverted, the same way as above using the group module how could i
proceed with this?

thanking you in advance
Phillip
