Thank you Daniel and Morten for your assistance and prompt reply.
To use the tobody transformation, i see that i would need to upgrade to 4.1 right? Im currently on 3.3. I tried the below code:
$var(i)=0; while($(hdr(Diversion)[$var(i)]) != $null ) {
$avp(s:divhdr) = $(hdr(Diversion)[$var(i)]); avp_subst("$avp(s:divhdr)", "/.*sip:(.*)(@.*)/\1/"); xlog("L_WARN", "$avp(s:divhdr)"); if (!is_user_in("$avp(s:divhdr)", "7")) { sl_send_reply("403", "NOT ALLOWED"); exit; };
$var(i) = $var(i) +1; }
However, it seems like group module cant parse the output 313 as seen below:
Apr 10 13:16:43 SipProxy-Test /usr/local/sbin/kamailio[7471]: WARNING: <script>: 313 Apr 10 13:16:43 SipProxy-Test /usr/local/sbin/kamailio[7471]: ERROR: group [group.c:114]: failed to parse URI <313> Apr 10 13:16:43 SipProxy-Test /usr/local/sbin/kamailio[7471]: ERROR: group [group.c:158]: failed to get username@domain
A bigger issue is that a certain client is sending more than one diversion header with different format as seen below:
Diversion: tel:22030009;reason=no-answer;screen=no;privacy=off Diversion: "Solonas A" sip:16@10.10.10.22;reason=unconditional
So in this case i cant really know how to extract the diversion number using a static substitution. Is there a way to adapt to different formats to extract the diversion number?
Thanking you in advance Phillip

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:

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; }/Morten
